MATHEMATICS Higher Level The portfolio – IA tasks For use in 2012 and 2013 SHADOW FUNCTIONS HL TYPE I
While real zeros of polynomial functions may be easily read off the graph of the polynomial, the same is not true for complex zeros. In this task, you will investigate the method of shadow functions and their generators, which helps identify the real and imaginary components of complex zeros from key points along the x-axis. Part A (Quadratic Polynomials) Consider the quadratic function 2 2 Write down the coordinates of the vertex. Show that 1 y has zeros, where.
_ How can the findings with quadratics and cubics be applied to quartics? PATTERNS FROM COMPLEX NUMBERS HL TYPE I To the student: The work that you produce to address the questions in this task should be a report that can stand on its own. It is best to avoid copying the questions in the task to adopt a “question and answer” format.
THE DICE GAME HL Type II To the student: The work that you produce to address the questions in this task should be a report that can stand on its own. It is best to avoid copying the questions in the task to adopt a “question and answer” format. The aim of this task is to create a dice game in a casino and model this using probability. It is important to examine how best to run the game from both the perspective of a player and the casino. In doing so analyse the game to consider the optimal payments by the player and payouts by the casino. _ Consider a game with two players, Ann and Bob. Ann has a red die and Bob a white die.
_ Now consider other models for the game including cases such as where the player or the bank rolls their dice multiple times, or where multiple players are involved in the game. FILLING UP THE PETROL TANK HL Type II To the student: The work that you produce to address the questions in this task should be a report that can stand on its own. It is best to avoid copying the questions in the task to adopt a “question and answer” format. In this task, you will develop a mathematical model that helps motorists decide which of the following two options is more economical. Option 1: to buy petrol from a station on their normal route at a relatively higher price. Option 2: to drive an extra distance out of their normal route to buy cheaper petrol. Consider a situation in which two motorists, Arwa and Bao, share the same driving route but own different sized vehicles. Arwa fills up her vehicle’s tank at a station along her normal route for US$ 1 p per litre. On the other hand, Bao drives an extra d kilometres out of his normal route to fill up his vehicle’s tank for US$ p2 per litre where p2 _ p1 .

SHADOW FUNCTIONS HL TYPE ITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo formatWhile real zeros of polynomial functions may be easily read off the graph of thepolynomial the same is not true for complex zeros In this task you will investigate themethod of shadow functions and their generators which helps identify the real andimaginary components of complex zeros from key points along the x-axisPart A (Quadratic Polynomials)
Consider the quadratic function 2 2Write down the coordinates of the vertexShow that 1 y has zeros whereThe ldquoshadow functionrdquo to 1 y is another quadratic 2 y which shares the same vertex asHowever 2 y has opposite concavity to that of 1 y and its zeros are in the form
Use various values for a and b to generate pairs of functions 1 y and
Hence or otherwise express 2 y in terms of 1 y and m y where m y is called the ldquoshadowgenerating functionrdquo_ On a labelled diagram illustrate how the zeros of 2 y may be helpful in the determination
of the real and imaginary components of the complex zeros of 1 y
Part B (Cubic Polynomials)Now consider the cubic function 1 _ _ _ _ y _ (x _ 2) x _ (3_ 2i) x _ (3_ 2i) The shadow function in this case is another cubic function 2 y which shares two points with 1 y has opposite concavity and its zeros are _2 and 3_ 2 as depicted in the figure below The shadow
generating function in this case passes through the two points of intersection
Write down an expression for 2 y and hence find the points of intersection between 1 y and 2 y
_ Hence or otherwise determine the equation of the shadow generating function m y in thiscase_ Once again express 2 y in terms of 1 y and m y Use technology to investigate similarcubic functions_ Write a general statement about the functions 1 y 2 y and m y and prove your statement_ On a labelled diagram illustrate how the zeros of 2 y may be helpful in the determinationof the real and imaginary components of the complex zeros of 1 y
_ How can the findings with quadratics and cubics be applied to quartics
PATTERNS FROM COMPLEX NUMBERS HL TYPE ITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo format
Part A
Use de Moivrersquos theorem to obtain solutions to the equation z3 _1 _ 0 _ Use graphing software to plot these roots on an Argand diagram as well as a unit circlewith centre origin_ Choose a root and draw line segments from this root to the other two roots
_ Measure these line segments and comment on your results_ Repeat the above for the equations z4 _1 _ 0 and z5 _1 _ 0 Comment on your results andtry to formulate a conjecture_ Factorize zn _1 for n _ 3 4 and 5_ Use graphing software to test your conjecture for some more values of n 1048576 __ and makemodifications to your conjecture if necessary_ Prove your conjecture
Part B
Use de Moivrersquos theorem to obtain solutions to zn _ i for n _ 3 4 and 5_ Use graphing software to represent each of these solutions on an Argand diagram_ Generalize and prove your results for zn _ a _ bi where a _ bi _1
_ What happens when a _ bi _1
THE DICE GAME HL Type IITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo formatThe aim of this task is to create a dice game in a casino and model this usingprobability It is important to examine how best to run the game from both the
perspective of a player and the casino In doing so analyse the game to consider theoptimal payments by the player and payouts by the casino_ Consider a game with two players Ann and Bob Ann has a red die and Bob a white dieThey roll their dice and note the number on the upper face Ann wins if her score is higherthan Bobrsquos (note that Bob wins if the scores are the same) If both players roll their diceonce each what is the probability that Ann will win the game_ Now consider the same game where Ann can roll her die a second time and will note thehigher score of the two rolls but Bob rolls only once In this case what is the probabilitythat Ann will win_ Investigate the game when both players can roll their dice twice and also when bothplayers can roll their dice more than twice but not necessarily the same number of times_ Consider the game in a casino where the player has a red die and the bank has a white dieFind a model for a game so that the casino makes a reasonable profit in the case where theplayer rolls the red die once and the bank rolls the white die once (When creating yourmodel you will need to consider how much a player must pay to play a game and howmuch the bank will pay out if the player wins Do this from the perspective of both theplayer and the casino and consider carefully the criteria for whether the game can be
considered worthwhile for both the player and the casino)_ Now consider other models for the game including cases such as where the player or the
bank rolls their dice multiple times or where multiple players are involved in the game

Basic Elements of a Good IB Mathematics Portfolio IB Math Internal Assessment (IA) Task HLSL Type 2 Type 1 Project
Correct answers throughout
All questions answered in a logical order
Audience is the teacher
Identify and address the principal goal of the assignment
Written explanations of difficult or less obvious steps in work
Word-processed including use of technology for graphs and equations
Elements of Superior Work
Attention to detail
Consistent use of significant figures or decimal place rounding
Use of proper notation such as ldquoasymprdquo or approximations
Avoid calculator notation such as 45 x^2 or 23E4
Graphs are clear with logical scales and labeled axes
Clearly define all variable that are introduced
Work stands alone
Audience is another student of the same level
Reader doesnrsquot have to refer to the assignment sheet
Reads smoothly and effortlessly
Answers are not numbered unless required
Single word-processed document
Integrate an equation-writing program spreadsheets graphing program etc
Comment on everything included
Explain all steps each time a new mathematical process is used
Avoid repetition of processes already explained
Graphs charts etc appear on the same page where they are explained
Student goes beyond the assignment with insight and sophistication
Identify and address the hidden goals of the assignment
Try to get into the mind of the writer of the assignment
Most tasks leave some space for the top students to explore
Student uses a variety of mathematical approaches
A good assignment will require the use of many kinds of math
A good question will often have several possible approaches for the solution
All math used is relevant to the task
No fluff or space-fillers
Tips to the Students
Work through all problems with pencil and calculator before writing it up
Gives an overall feel for the project so that that student can start to address the main goal and
even insights right from the start
Write a brief introduction rather than jumping right in to the first question
Sets a tone of readability
Math SLHL students can pretend that they are writing a chapter in a textbook
Encourages students to fully explain each step remembering that their audience is another
student from their course of average ability
Students can have fun with creative formatting
Take pride in the look and feel of their work
Math Studies students can approach the IA Project as they would a science lab
Write a hypothesis
Collect data
Analyze data
Draw conclusions
Discuss possible errors or improvements
Common Problems
Solutions to individual problems are cut in half by the page break
It is ok to leave space on the bottom of a page
Use the ldquoInsert Page-Breakrdquo feature of most word-processing programs when a new problem is
started (If there is not enough space on the current page)
Proof for comments like ldquosee the graph belowrdquo when the graph was accidentally bumped to the
next page during editing
Pages of graphs or charts with comments and explanations at end
Full-page graphs should be avoided if possible
Include small (but clear) graphs with an explanation on the same page
Use features like ldquotext-wrappingrdquo to make graphs or charts look and feel like an integrated part
of the work
If a graph must take up a full page include a full discussion of it on the next page
Pages of raw data in the main body of text
Raw data should be organized as concisely as possible and included in the appendix
The main body should only include the compiled data used in the relevant calculation
Frequent reference to appendix
Cuts the flow of the work
If what is in the appendix is very important move it to the body
Over-researching
IB Math Internal Assessments are not research projects
IB is looking for student work and it is obvious when it is not
Grading
Read paper from start to finish before assigning grades
Detail is important
Overall feel is important
Make comments or corrections in the text
Comments help the IB moderator to understand how you have assigned marks
Reference the IB Rubric on a regular basis
IB has two rubrics which could be used for students at many levels
Math Studies (Open-ended project)

SHADOW FUNCTIONS HL TYPE ITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo formatWhile real zeros of polynomial functions may be easily read off the graph of thepolynomial the same is not true for complex zeros In this task you will investigate themethod of shadow functions and their generators which helps identify the real andimaginary components of complex zeros from key points along the x-axisPart A (Quadratic Polynomials)
Consider the quadratic function 2 2Write down the coordinates of the vertexShow that 1 y has zeros whereThe ldquoshadow functionrdquo to 1 y is another quadratic 2 y which shares the same vertex asHowever 2 y has opposite concavity to that of 1 y and its zeros are in the form
Use various values for a and b to generate pairs of functions 1 y and
Hence or otherwise express 2 y in terms of 1 y and m y where m y is called the ldquoshadowgenerating functionrdquo_ On a labelled diagram illustrate how the zeros of 2 y may be helpful in the determination
of the real and imaginary components of the complex zeros of 1 y
Part B (Cubic Polynomials)Now consider the cubic function 1 _ _ _ _ y _ (x _ 2) x _ (3_ 2i) x _ (3_ 2i) The shadow function in this case is another cubic function 2 y which shares two points with 1 y has opposite concavity and its zeros are _2 and 3_ 2 as depicted in the figure below The shadow
generating function in this case passes through the two points of intersection
Write down an expression for 2 y and hence find the points of intersection between 1 y and 2 y
_ Hence or otherwise determine the equation of the shadow generating function m y in thiscase_ Once again express 2 y in terms of 1 y and m y Use technology to investigate similarcubic functions_ Write a general statement about the functions 1 y 2 y and m y and prove your statement_ On a labelled diagram illustrate how the zeros of 2 y may be helpful in the determinationof the real and imaginary components of the complex zeros of 1 y
_ How can the findings with quadratics and cubics be applied to quartics
PATTERNS FROM COMPLEX NUMBERS HL TYPE ITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo format
Part A
Use de Moivrersquos theorem to obtain solutions to the equation z3 _1 _ 0 _ Use graphing software to plot these roots on an Argand diagram as well as a unit circlewith centre origin_ Choose a root and draw line segments from this root to the other two roots
_ Measure these line segments and comment on your results_ Repeat the above for the equations z4 _1 _ 0 and z5 _1 _ 0 Comment on your results andtry to formulate a conjecture_ Factorize zn _1 for n _ 3 4 and 5_ Use graphing software to test your conjecture for some more values of n 1048576 __ and makemodifications to your conjecture if necessary_ Prove your conjecture
Part B
Use de Moivrersquos theorem to obtain solutions to zn _ i for n _ 3 4 and 5_ Use graphing software to represent each of these solutions on an Argand diagram_ Generalize and prove your results for zn _ a _ bi where a _ bi _1
_ What happens when a _ bi _1
THE DICE GAME HL Type IITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo formatThe aim of this task is to create a dice game in a casino and model this usingprobability It is important to examine how best to run the game from both the
perspective of a player and the casino In doing so analyse the game to consider theoptimal payments by the player and payouts by the casino_ Consider a game with two players Ann and Bob Ann has a red die and Bob a white dieThey roll their dice and note the number on the upper face Ann wins if her score is higherthan Bobrsquos (note that Bob wins if the scores are the same) If both players roll their diceonce each what is the probability that Ann will win the game_ Now consider the same game where Ann can roll her die a second time and will note thehigher score of the two rolls but Bob rolls only once In this case what is the probabilitythat Ann will win_ Investigate the game when both players can roll their dice twice and also when bothplayers can roll their dice more than twice but not necessarily the same number of times_ Consider the game in a casino where the player has a red die and the bank has a white dieFind a model for a game so that the casino makes a reasonable profit in the case where theplayer rolls the red die once and the bank rolls the white die once (When creating yourmodel you will need to consider how much a player must pay to play a game and howmuch the bank will pay out if the player wins Do this from the perspective of both theplayer and the casino and consider carefully the criteria for whether the game can be
considered worthwhile for both the player and the casino)_ Now consider other models for the game including cases such as where the player or the
bank rolls their dice multiple times or where multiple players are involved in the game
FILLING UP THE PETROL TANK HL Type IITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo formatIn this task you will develop a mathematical model that helps motorists decide which ofthe following two options is more economicalOption 1 to buy petrol from a station on their normal route at a relatively higher priceOption 2 to drive an extra distance out of their normal route to buy cheaper petrolConsider a situation in which two motorists Arwa and Bao share the same driving route but owndifferent sized vehicles Arwa fills up her vehiclersquos tank at a station along her normal route forUS$ 1 p per litre On the other hand Bao drives an extra d kilometres out of his normal route to fillup his vehiclersquos tank for US$ p2 per litre where p2 _ p1 _ Choose suitable parameters for Arwarsquos and Baorsquos vehicles Justify your choices
_ Suppose 1 p _ US$100 per litre 2 p _ US$098 per litre and d _10 km Which motorist is getting the better deal Show all calculations and justify any assumptions you make_ On a spreadsheet choose several sets of values for 1 p 2 p and d to investigate further_ Define a set of variables that would be relevant in the above situationldquoEffective litresrdquo is a method of comparing the cost of petrol bought under the two optionsdescribed above Effective litres for a given vehicle are those litres used when the vehicle travelsits normal route_ Use your variables and parameters to write algebraic expressions for 1 E and 2 E whichrepresent the cost per effective litre under options 1 and 2 respectively_ Write a model that helps motorists decide on the more economical option for theirvehiclesIn the remainder of this task you need to consider the two vehicles you have chosen for Arwaand Bao_ Use your model to find the farthest distance that Bao should drive to obtain a 2 pricesaving_ Investigate the relationship between d and 2 p when 2 E is kept constant (eg US$090US$100 hellip etc) Use technology to draw a family of curves for Arwarsquos vehicle Repeatfor Baorsquos vehicle
_ For 2 E _ US$090 provide Arwa with information on three different stations that yieldthis same cost per effective litre Discuss how such information may be useful to Arwa_ For 2 E _ US$100 and 2 p _ US$080 compare the maximum distance that each motoristshould drive and still save moneyArwa is a busy person and wonders whether the saving in money would be worth the time shewould lose in extra driving_ Modify your model to account for the time taken to drive to and from an off-route station

All questions answered in a logical order
Audience is the teacher
Identify and address the principal goal of the assignment
Written explanations of difficult or less obvious steps in work
Word-processed including use of technology for graphs and equations
Elements of Superior Work
Attention to detail
Consistent use of significant figures or decimal place rounding
Use of proper notation such as ldquoasymprdquo or approximations
Avoid calculator notation such as 45 x^2 or 23E4
Graphs are clear with logical scales and labeled axes
Clearly define all variable that are introduced
Work stands alone
Audience is another student of the same level
Reader doesnrsquot have to refer to the assignment sheet
Reads smoothly and effortlessly
Answers are not numbered unless required
Single word-processed document
Integrate an equation-writing program spreadsheets graphing program etc
Comment on everything included
Explain all steps each time a new mathematical process is used
Avoid repetition of processes already explained
Graphs charts etc appear on the same page where they are explained
Student goes beyond the assignment with insight and sophistication
Identify and address the hidden goals of the assignment
Try to get into the mind of the writer of the assignment
Most tasks leave some space for the top students to explore
Student uses a variety of mathematical approaches
A good assignment will require the use of many kinds of math
A good question will often have several possible approaches for the solution
All math used is relevant to the task
No fluff or space-fillers
Tips to the Students
Work through all problems with pencil and calculator before writing it up
Gives an overall feel for the project so that that student can start to address the main goal and
even insights right from the start
Write a brief introduction rather than jumping right in to the first question
Sets a tone of readability
Math SLHL students can pretend that they are writing a chapter in a textbook
Encourages students to fully explain each step remembering that their audience is another
student from their course of average ability
Students can have fun with creative formatting
Take pride in the look and feel of their work
Math Studies students can approach the IA Project as they would a science lab
Write a hypothesis
Collect data
Analyze data
Draw conclusions
Discuss possible errors or improvements
Common Problems
Solutions to individual problems are cut in half by the page break
It is ok to leave space on the bottom of a page
Use the ldquoInsert Page-Breakrdquo feature of most word-processing programs when a new problem is
started (If there is not enough space on the current page)
Proof for comments like ldquosee the graph belowrdquo when the graph was accidentally bumped to the
next page during editing
Pages of graphs or charts with comments and explanations at end
Full-page graphs should be avoided if possible
Include small (but clear) graphs with an explanation on the same page
Use features like ldquotext-wrappingrdquo to make graphs or charts look and feel like an integrated part
of the work
If a graph must take up a full page include a full discussion of it on the next page
Pages of raw data in the main body of text
Raw data should be organized as concisely as possible and included in the appendix
The main body should only include the compiled data used in the relevant calculation
Frequent reference to appendix
Cuts the flow of the work
If what is in the appendix is very important move it to the body
Over-researching
IB Math Internal Assessments are not research projects
IB is looking for student work and it is obvious when it is not
Grading
Read paper from start to finish before assigning grades
Detail is important
Overall feel is important
Make comments or corrections in the text
Comments help the IB moderator to understand how you have assigned marks
Reference the IB Rubric on a regular basis
IB has two rubrics which could be used for students at many levels
Math Studies (Open-ended project)

Basic Elements of a Good IB Mathematics Portfolio IB Math Internal Assessment (IA) Task HLSL Type 2 Type 1 Project
Correct answers throughout
All questions answered in a logical order
Audience is the teacher
Identify and address the principal goal of the assignment
Written explanations of difficult or less obvious steps in work
Word-processed including use of technology for graphs and equations
Elements of Superior Work
Attention to detail
Consistent use of significant figures or decimal place rounding
Use of proper notation such as ldquoasymprdquo or approximations
Avoid calculator notation such as 45 x^2 or 23E4
Graphs are clear with logical scales and labeled axes
Clearly define all variable that are introduced
Work stands alone
Audience is another student of the same level
Reader doesnrsquot have to refer to the assignment sheet
Reads smoothly and effortlessly
Answers are not numbered unless required
Single word-processed document
Integrate an equation-writing program spreadsheets graphing program etc
Comment on everything included
Explain all steps each time a new mathematical process is used
Avoid repetition of processes already explained
Graphs charts etc appear on the same page where they are explained
Student goes beyond the assignment with insight and sophistication
Identify and address the hidden goals of the assignment
Try to get into the mind of the writer of the assignment
Most tasks leave some space for the top students to explore
Student uses a variety of mathematical approaches
A good assignment will require the use of many kinds of math
A good question will often have several possible approaches for the solution
All math used is relevant to the task
No fluff or space-fillers
Tips to the Students
Work through all problems with pencil and calculator before writing it up
Gives an overall feel for the project so that that student can start to address the main goal and
even insights right from the start
Write a brief introduction rather than jumping right in to the first question
Sets a tone of readability
Math SLHL students can pretend that they are writing a chapter in a textbook
Encourages students to fully explain each step remembering that their audience is another
student from their course of average ability
Students can have fun with creative formatting
Take pride in the look and feel of their work
Math Studies students can approach the IA Project as they would a science lab
Write a hypothesis
Collect data
Analyze data
Draw conclusions
Discuss possible errors or improvements
Common Problems
Solutions to individual problems are cut in half by the page break
It is ok to leave space on the bottom of a page
Use the ldquoInsert Page-Breakrdquo feature of most word-processing programs when a new problem is
started (If there is not enough space on the current page)
Proof for comments like ldquosee the graph belowrdquo when the graph was accidentally bumped to the
next page during editing
Pages of graphs or charts with comments and explanations at end
Full-page graphs should be avoided if possible
Include small (but clear) graphs with an explanation on the same page
Use features like ldquotext-wrappingrdquo to make graphs or charts look and feel like an integrated part
of the work
If a graph must take up a full page include a full discussion of it on the next page
Pages of raw data in the main body of text
Raw data should be organized as concisely as possible and included in the appendix
The main body should only include the compiled data used in the relevant calculation
Frequent reference to appendix
Cuts the flow of the work
If what is in the appendix is very important move it to the body
Over-researching
IB Math Internal Assessments are not research projects
IB is looking for student work and it is obvious when it is not
Grading
Read paper from start to finish before assigning grades
Detail is important
Overall feel is important
Make comments or corrections in the text
Comments help the IB moderator to understand how you have assigned marks
Reference the IB Rubric on a regular basis
IB has two rubrics which could be used for students at many levels
Math Studies (Open-ended project)
Math SLHL (Answering an assigned problem)

SHADOW FUNCTIONS HL TYPE ITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo formatWhile real zeros of polynomial functions may be easily read off the graph of thepolynomial the same is not true for complex zeros In this task you will investigate themethod of shadow functions and their generators which helps identify the real andimaginary components of complex zeros from key points along the x-axisPart A (Quadratic Polynomials)
Consider the quadratic function 2 2Write down the coordinates of the vertexShow that 1 y has zeros whereThe ldquoshadow functionrdquo to 1 y is another quadratic 2 y which shares the same vertex asHowever 2 y has opposite concavity to that of 1 y and its zeros are in the form
Use various values for a and b to generate pairs of functions 1 y and
Hence or otherwise express 2 y in terms of 1 y and m y where m y is called the ldquoshadowgenerating functionrdquo_ On a labelled diagram illustrate how the zeros of 2 y may be helpful in the determination
of the real and imaginary components of the complex zeros of 1 y
Part B (Cubic Polynomials)Now consider the cubic function 1 _ _ _ _ y _ (x _ 2) x _ (3_ 2i) x _ (3_ 2i) The shadow function in this case is another cubic function 2 y which shares two points with 1 y has opposite concavity and its zeros are _2 and 3_ 2 as depicted in the figure below The shadow
generating function in this case passes through the two points of intersection
Write down an expression for 2 y and hence find the points of intersection between 1 y and 2 y
_ Hence or otherwise determine the equation of the shadow generating function m y in thiscase_ Once again express 2 y in terms of 1 y and m y Use technology to investigate similarcubic functions_ Write a general statement about the functions 1 y 2 y and m y and prove your statement_ On a labelled diagram illustrate how the zeros of 2 y may be helpful in the determinationof the real and imaginary components of the complex zeros of 1 y
_ How can the findings with quadratics and cubics be applied to quartics
PATTERNS FROM COMPLEX NUMBERS HL TYPE ITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo format
Part A
Use de Moivrersquos theorem to obtain solutions to the equation z3 _1 _ 0 _ Use graphing software to plot these roots on an Argand diagram as well as a unit circlewith centre origin_ Choose a root and draw line segments from this root to the other two roots
_ Measure these line segments and comment on your results_ Repeat the above for the equations z4 _1 _ 0 and z5 _1 _ 0 Comment on your results andtry to formulate a conjecture_ Factorize zn _1 for n _ 3 4 and 5_ Use graphing software to test your conjecture for some more values of n 1048576 __ and makemodifications to your conjecture if necessary_ Prove your conjecture
Part B
Use de Moivrersquos theorem to obtain solutions to zn _ i for n _ 3 4 and 5_ Use graphing software to represent each of these solutions on an Argand diagram_ Generalize and prove your results for zn _ a _ bi where a _ bi _1
_ What happens when a _ bi _1
THE DICE GAME HL Type IITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo formatThe aim of this task is to create a dice game in a casino and model this usingprobability It is important to examine how best to run the game from both the
perspective of a player and the casino In doing so analyse the game to consider theoptimal payments by the player and payouts by the casino_ Consider a game with two players Ann and Bob Ann has a red die and Bob a white dieThey roll their dice and note the number on the upper face Ann wins if her score is higherthan Bobrsquos (note that Bob wins if the scores are the same) If both players roll their diceonce each what is the probability that Ann will win the game_ Now consider the same game where Ann can roll her die a second time and will note thehigher score of the two rolls but Bob rolls only once In this case what is the probabilitythat Ann will win_ Investigate the game when both players can roll their dice twice and also when bothplayers can roll their dice more than twice but not necessarily the same number of times_ Consider the game in a casino where the player has a red die and the bank has a white dieFind a model for a game so that the casino makes a reasonable profit in the case where theplayer rolls the red die once and the bank rolls the white die once (When creating yourmodel you will need to consider how much a player must pay to play a game and howmuch the bank will pay out if the player wins Do this from the perspective of both theplayer and the casino and consider carefully the criteria for whether the game can be
considered worthwhile for both the player and the casino)_ Now consider other models for the game including cases such as where the player or the
bank rolls their dice multiple times or where multiple players are involved in the game
FILLING UP THE PETROL TANK HL Type IITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo formatIn this task you will develop a mathematical model that helps motorists decide which ofthe following two options is more economicalOption 1 to buy petrol from a station on their normal route at a relatively higher priceOption 2 to drive an extra distance out of their normal route to buy cheaper petrolConsider a situation in which two motorists Arwa and Bao share the same driving route but owndifferent sized vehicles Arwa fills up her vehiclersquos tank at a station along her normal route forUS$ 1 p per litre On the other hand Bao drives an extra d kilometres out of his normal route to fillup his vehiclersquos tank for US$ p2 per litre where p2 _ p1 _ Choose suitable parameters for Arwarsquos and Baorsquos vehicles Justify your choices
_ Suppose 1 p _ US$100 per litre 2 p _ US$098 per litre and d _10 km Which motorist is getting the better deal Show all calculations and justify any assumptions you make_ On a spreadsheet choose several sets of values for 1 p 2 p and d to investigate further_ Define a set of variables that would be relevant in the above situationldquoEffective litresrdquo is a method of comparing the cost of petrol bought under the two optionsdescribed above Effective litres for a given vehicle are those litres used when the vehicle travelsits normal route_ Use your variables and parameters to write algebraic expressions for 1 E and 2 E whichrepresent the cost per effective litre under options 1 and 2 respectively_ Write a model that helps motorists decide on the more economical option for theirvehiclesIn the remainder of this task you need to consider the two vehicles you have chosen for Arwaand Bao_ Use your model to find the farthest distance that Bao should drive to obtain a 2 pricesaving_ Investigate the relationship between d and 2 p when 2 E is kept constant (eg US$090US$100 hellip etc) Use technology to draw a family of curves for Arwarsquos vehicle Repeatfor Baorsquos vehicle
_ For 2 E _ US$090 provide Arwa with information on three different stations that yieldthis same cost per effective litre Discuss how such information may be useful to Arwa_ For 2 E _ US$100 and 2 p _ US$080 compare the maximum distance that each motoristshould drive and still save moneyArwa is a busy person and wonders whether the saving in money would be worth the time shewould lose in extra driving_ Modify your model to account for the time taken to drive to and from an off-route station

SHADOW FUNCTIONS HL TYPE ITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo formatWhile real zeros of polynomial functions may be easily read off the graph of thepolynomial the same is not true for complex zeros In this task you will investigate themethod of shadow functions and their generators which helps identify the real andimaginary components of complex zeros from key points along the x-axisPart A (Quadratic Polynomials)
Consider the quadratic function 2 2Write down the coordinates of the vertexShow that 1 y has zeros whereThe ldquoshadow functionrdquo to 1 y is another quadratic 2 y which shares the same vertex asHowever 2 y has opposite concavity to that of 1 y and its zeros are in the form
Use various values for a and b to generate pairs of functions 1 y and
Hence or otherwise express 2 y in terms of 1 y and m y where m y is called the ldquoshadowgenerating functionrdquo_ On a labelled diagram illustrate how the zeros of 2 y may be helpful in the determination
of the real and imaginary components of the complex zeros of 1 y
Part B (Cubic Polynomials)Now consider the cubic function 1 _ _ _ _ y _ (x _ 2) x _ (3_ 2i) x _ (3_ 2i) The shadow function in this case is another cubic function 2 y which shares two points with 1 y has opposite concavity and its zeros are _2 and 3_ 2 as depicted in the figure below The shadow
generating function in this case passes through the two points of intersection
Write down an expression for 2 y and hence find the points of intersection between 1 y and 2 y
_ Hence or otherwise determine the equation of the shadow generating function m y in thiscase_ Once again express 2 y in terms of 1 y and m y Use technology to investigate similarcubic functions_ Write a general statement about the functions 1 y 2 y and m y and prove your statement_ On a labelled diagram illustrate how the zeros of 2 y may be helpful in the determinationof the real and imaginary components of the complex zeros of 1 y
_ How can the findings with quadratics and cubics be applied to quartics
PATTERNS FROM COMPLEX NUMBERS HL TYPE ITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo format
Part A
Use de Moivrersquos theorem to obtain solutions to the equation z3 _1 _ 0 _ Use graphing software to plot these roots on an Argand diagram as well as a unit circlewith centre origin_ Choose a root and draw line segments from this root to the other two roots
_ Measure these line segments and comment on your results_ Repeat the above for the equations z4 _1 _ 0 and z5 _1 _ 0 Comment on your results andtry to formulate a conjecture_ Factorize zn _1 for n _ 3 4 and 5_ Use graphing software to test your conjecture for some more values of n 1048576 __ and makemodifications to your conjecture if necessary_ Prove your conjecture
Part B
Use de Moivrersquos theorem to obtain solutions to zn _ i for n _ 3 4 and 5_ Use graphing software to represent each of these solutions on an Argand diagram_ Generalize and prove your results for zn _ a _ bi where a _ bi _1
_ What happens when a _ bi _1
THE DICE GAME HL Type IITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo formatThe aim of this task is to create a dice game in a casino and model this usingprobability It is important to examine how best to run the game from both the
perspective of a player and the casino In doing so analyse the game to consider theoptimal payments by the player and payouts by the casino_ Consider a game with two players Ann and Bob Ann has a red die and Bob a white dieThey roll their dice and note the number on the upper face Ann wins if her score is higherthan Bobrsquos (note that Bob wins if the scores are the same) If both players roll their diceonce each what is the probability that Ann will win the game_ Now consider the same game where Ann can roll her die a second time and will note thehigher score of the two rolls but Bob rolls only once In this case what is the probabilitythat Ann will win_ Investigate the game when both players can roll their dice twice and also when bothplayers can roll their dice more than twice but not necessarily the same number of times_ Consider the game in a casino where the player has a red die and the bank has a white dieFind a model for a game so that the casino makes a reasonable profit in the case where theplayer rolls the red die once and the bank rolls the white die once (When creating yourmodel you will need to consider how much a player must pay to play a game and howmuch the bank will pay out if the player wins Do this from the perspective of both theplayer and the casino and consider carefully the criteria for whether the game can be
considered worthwhile for both the player and the casino)_ Now consider other models for the game including cases such as where the player or the
bank rolls their dice multiple times or where multiple players are involved in the game
FILLING UP THE PETROL TANK HL Type IITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo formatIn this task you will develop a mathematical model that helps motorists decide which ofthe following two options is more economicalOption 1 to buy petrol from a station on their normal route at a relatively higher priceOption 2 to drive an extra distance out of their normal route to buy cheaper petrolConsider a situation in which two motorists Arwa and Bao share the same driving route but owndifferent sized vehicles Arwa fills up her vehiclersquos tank at a station along her normal route forUS$ 1 p per litre On the other hand Bao drives an extra d kilometres out of his normal route to fillup his vehiclersquos tank for US$ p2 per litre where p2 _ p1 _ Choose suitable parameters for Arwarsquos and Baorsquos vehicles Justify your choices
_ Suppose 1 p _ US$100 per litre 2 p _ US$098 per litre and d _10 km Which motorist is getting the better deal Show all calculations and justify any assumptions you make_ On a spreadsheet choose several sets of values for 1 p 2 p and d to investigate further_ Define a set of variables that would be relevant in the above situationldquoEffective litresrdquo is a method of comparing the cost of petrol bought under the two optionsdescribed above Effective litres for a given vehicle are those litres used when the vehicle travelsits normal route_ Use your variables and parameters to write algebraic expressions for 1 E and 2 E whichrepresent the cost per effective litre under options 1 and 2 respectively_ Write a model that helps motorists decide on the more economical option for theirvehiclesIn the remainder of this task you need to consider the two vehicles you have chosen for Arwaand Bao_ Use your model to find the farthest distance that Bao should drive to obtain a 2 pricesaving_ Investigate the relationship between d and 2 p when 2 E is kept constant (eg US$090US$100 hellip etc) Use technology to draw a family of curves for Arwarsquos vehicle Repeatfor Baorsquos vehicle

Basic Elements of a Good IB Mathematics Portfolio IB Math Internal Assessment (IA) Task HLSL Type 2 Type 1 Project
Correct answers throughout
All questions answered in a logical order
Audience is the teacher
Identify and address the principal goal of the assignment
Written explanations of difficult or less obvious steps in work
Word-processed including use of technology for graphs and equations
Elements of Superior Work
Attention to detail
Consistent use of significant figures or decimal place rounding
Use of proper notation such as ldquoasymprdquo or approximations
Avoid calculator notation such as 45 x^2 or 23E4
Graphs are clear with logical scales and labeled axes
Clearly define all variable that are introduced
Work stands alone
Audience is another student of the same level
Reader doesnrsquot have to refer to the assignment sheet
Reads smoothly and effortlessly
Answers are not numbered unless required
Single word-processed document
Integrate an equation-writing program spreadsheets graphing program etc
Comment on everything included
Explain all steps each time a new mathematical process is used
Avoid repetition of processes already explained
Graphs charts etc appear on the same page where they are explained
Student goes beyond the assignment with insight and sophistication
Identify and address the hidden goals of the assignment
Try to get into the mind of the writer of the assignment
Most tasks leave some space for the top students to explore
Student uses a variety of mathematical approaches
A good assignment will require the use of many kinds of math
A good question will often have several possible approaches for the solution
All math used is relevant to the task
No fluff or space-fillers
Tips to the Students
Work through all problems with pencil and calculator before writing it up
Gives an overall feel for the project so that that student can start to address the main goal and
even insights right from the start
Write a brief introduction rather than jumping right in to the first question
Sets a tone of readability
Math SLHL students can pretend that they are writing a chapter in a textbook
Encourages students to fully explain each step remembering that their audience is another
student from their course of average ability
Students can have fun with creative formatting
Take pride in the look and feel of their work
Math Studies students can approach the IA Project as they would a science lab
Write a hypothesis
Collect data
Analyze data
Draw conclusions
Discuss possible errors or improvements
Common Problems
Solutions to individual problems are cut in half by the page break
It is ok to leave space on the bottom of a page
Use the ldquoInsert Page-Breakrdquo feature of most word-processing programs when a new problem is
started (If there is not enough space on the current page)
Proof for comments like ldquosee the graph belowrdquo when the graph was accidentally bumped to the
next page during editing
Pages of graphs or charts with comments and explanations at end
Full-page graphs should be avoided if possible
Include small (but clear) graphs with an explanation on the same page
Use features like ldquotext-wrappingrdquo to make graphs or charts look and feel like an integrated part
of the work
If a graph must take up a full page include a full discussion of it on the next page
Pages of raw data in the main body of text
Raw data should be organized as concisely as possible and included in the appendix
The main body should only include the compiled data used in the relevant calculation
Frequent reference to appendix
Cuts the flow of the work
If what is in the appendix is very important move it to the body
Over-researching
IB Math Internal Assessments are not research projects
IB is looking for student work and it is obvious when it is not
Grading
Read paper from start to finish before assigning grades
Detail is important
Overall feel is important
Make comments or corrections in the text
Comments help the IB moderator to understand how you have assigned marks
Reference the IB Rubric on a regular basis
IB has two rubrics which could be used for students at many levels
Math Studies (Open-ended project)
Math SLHL (Answering an assigned problem)

Identify and address the principal goal of the assignment
Written explanations of difficult or less obvious steps in work
Word-processed including use of technology for graphs and equations
Elements of Superior Work
Attention to detail
Consistent use of significant figures or decimal place rounding
Use of proper notation such as ldquoasymprdquo or approximations
Avoid calculator notation such as 45 x^2 or 23E4
Graphs are clear with logical scales and labeled axes
Clearly define all variable that are introduced
Work stands alone
Audience is another student of the same level
Reader doesnrsquot have to refer to the assignment sheet
Reads smoothly and effortlessly
Answers are not numbered unless required
Single word-processed document
Integrate an equation-writing program spreadsheets graphing program etc
Comment on everything included
Explain all steps each time a new mathematical process is used
Avoid repetition of processes already explained
Graphs charts etc appear on the same page where they are explained
Student goes beyond the assignment with insight and sophistication
Identify and address the hidden goals of the assignment
Try to get into the mind of the writer of the assignment
Most tasks leave some space for the top students to explore
Student uses a variety of mathematical approaches
A good assignment will require the use of many kinds of math
A good question will often have several possible approaches for the solution
All math used is relevant to the task
No fluff or space-fillers
Tips to the Students
Work through all problems with pencil and calculator before writing it up
Gives an overall feel for the project so that that student can start to address the main goal and
even insights right from the start
Write a brief introduction rather than jumping right in to the first question
Sets a tone of readability
Math SLHL students can pretend that they are writing a chapter in a textbook
Encourages students to fully explain each step remembering that their audience is another
student from their course of average ability
Students can have fun with creative formatting
Take pride in the look and feel of their work
Math Studies students can approach the IA Project as they would a science lab
Write a hypothesis
Collect data
Analyze data
Draw conclusions
Discuss possible errors or improvements
Common Problems
Solutions to individual problems are cut in half by the page break
It is ok to leave space on the bottom of a page
Use the ldquoInsert Page-Breakrdquo feature of most word-processing programs when a new problem is
started (If there is not enough space on the current page)
Proof for comments like ldquosee the graph belowrdquo when the graph was accidentally bumped to the
next page during editing
Pages of graphs or charts with comments and explanations at end
Full-page graphs should be avoided if possible
Include small (but clear) graphs with an explanation on the same page
Use features like ldquotext-wrappingrdquo to make graphs or charts look and feel like an integrated part
of the work
If a graph must take up a full page include a full discussion of it on the next page
Pages of raw data in the main body of text
Raw data should be organized as concisely as possible and included in the appendix
The main body should only include the compiled data used in the relevant calculation
Frequent reference to appendix
Cuts the flow of the work
If what is in the appendix is very important move it to the body
Over-researching
IB Math Internal Assessments are not research projects
IB is looking for student work and it is obvious when it is not
Grading
Read paper from start to finish before assigning grades
Detail is important
Overall feel is important
Make comments or corrections in the text
Comments help the IB moderator to understand how you have assigned marks
Reference the IB Rubric on a regular basis
IB has two rubrics which could be used for students at many levels

SHADOW FUNCTIONS HL TYPE ITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo formatWhile real zeros of polynomial functions may be easily read off the graph of thepolynomial the same is not true for complex zeros In this task you will investigate themethod of shadow functions and their generators which helps identify the real andimaginary components of complex zeros from key points along the x-axisPart A (Quadratic Polynomials)
Consider the quadratic function 2 2Write down the coordinates of the vertexShow that 1 y has zeros whereThe ldquoshadow functionrdquo to 1 y is another quadratic 2 y which shares the same vertex asHowever 2 y has opposite concavity to that of 1 y and its zeros are in the form
Use various values for a and b to generate pairs of functions 1 y and
Hence or otherwise express 2 y in terms of 1 y and m y where m y is called the ldquoshadowgenerating functionrdquo_ On a labelled diagram illustrate how the zeros of 2 y may be helpful in the determination
of the real and imaginary components of the complex zeros of 1 y
Part B (Cubic Polynomials)Now consider the cubic function 1 _ _ _ _ y _ (x _ 2) x _ (3_ 2i) x _ (3_ 2i) The shadow function in this case is another cubic function 2 y which shares two points with 1 y has opposite concavity and its zeros are _2 and 3_ 2 as depicted in the figure below The shadow
generating function in this case passes through the two points of intersection
Write down an expression for 2 y and hence find the points of intersection between 1 y and 2 y
_ Hence or otherwise determine the equation of the shadow generating function m y in thiscase_ Once again express 2 y in terms of 1 y and m y Use technology to investigate similarcubic functions_ Write a general statement about the functions 1 y 2 y and m y and prove your statement_ On a labelled diagram illustrate how the zeros of 2 y may be helpful in the determinationof the real and imaginary components of the complex zeros of 1 y
_ How can the findings with quadratics and cubics be applied to quartics
PATTERNS FROM COMPLEX NUMBERS HL TYPE ITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo format
Part A
Use de Moivrersquos theorem to obtain solutions to the equation z3 _1 _ 0 _ Use graphing software to plot these roots on an Argand diagram as well as a unit circlewith centre origin_ Choose a root and draw line segments from this root to the other two roots
_ Measure these line segments and comment on your results_ Repeat the above for the equations z4 _1 _ 0 and z5 _1 _ 0 Comment on your results andtry to formulate a conjecture_ Factorize zn _1 for n _ 3 4 and 5_ Use graphing software to test your conjecture for some more values of n 1048576 __ and makemodifications to your conjecture if necessary_ Prove your conjecture
Part B
Use de Moivrersquos theorem to obtain solutions to zn _ i for n _ 3 4 and 5_ Use graphing software to represent each of these solutions on an Argand diagram_ Generalize and prove your results for zn _ a _ bi where a _ bi _1
_ What happens when a _ bi _1
THE DICE GAME HL Type IITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo formatThe aim of this task is to create a dice game in a casino and model this usingprobability It is important to examine how best to run the game from both the
perspective of a player and the casino In doing so analyse the game to consider theoptimal payments by the player and payouts by the casino_ Consider a game with two players Ann and Bob Ann has a red die and Bob a white dieThey roll their dice and note the number on the upper face Ann wins if her score is higherthan Bobrsquos (note that Bob wins if the scores are the same) If both players roll their diceonce each what is the probability that Ann will win the game_ Now consider the same game where Ann can roll her die a second time and will note thehigher score of the two rolls but Bob rolls only once In this case what is the probabilitythat Ann will win_ Investigate the game when both players can roll their dice twice and also when bothplayers can roll their dice more than twice but not necessarily the same number of times_ Consider the game in a casino where the player has a red die and the bank has a white dieFind a model for a game so that the casino makes a reasonable profit in the case where theplayer rolls the red die once and the bank rolls the white die once (When creating yourmodel you will need to consider how much a player must pay to play a game and howmuch the bank will pay out if the player wins Do this from the perspective of both theplayer and the casino and consider carefully the criteria for whether the game can be
considered worthwhile for both the player and the casino)_ Now consider other models for the game including cases such as where the player or the
bank rolls their dice multiple times or where multiple players are involved in the game
FILLING UP THE PETROL TANK HL Type IITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo formatIn this task you will develop a mathematical model that helps motorists decide which ofthe following two options is more economicalOption 1 to buy petrol from a station on their normal route at a relatively higher priceOption 2 to drive an extra distance out of their normal route to buy cheaper petrolConsider a situation in which two motorists Arwa and Bao share the same driving route but owndifferent sized vehicles Arwa fills up her vehiclersquos tank at a station along her normal route forUS$ 1 p per litre On the other hand Bao drives an extra d kilometres out of his normal route to fillup his vehiclersquos tank for US$ p2 per litre where p2 _ p1 _ Choose suitable parameters for Arwarsquos and Baorsquos vehicles Justify your choices
_ Suppose 1 p _ US$100 per litre 2 p _ US$098 per litre and d _10 km Which motorist is getting the better deal Show all calculations and justify any assumptions you make_ On a spreadsheet choose several sets of values for 1 p 2 p and d to investigate further_ Define a set of variables that would be relevant in the above situationldquoEffective litresrdquo is a method of comparing the cost of petrol bought under the two optionsdescribed above Effective litres for a given vehicle are those litres used when the vehicle travelsits normal route_ Use your variables and parameters to write algebraic expressions for 1 E and 2 E whichrepresent the cost per effective litre under options 1 and 2 respectively_ Write a model that helps motorists decide on the more economical option for theirvehiclesIn the remainder of this task you need to consider the two vehicles you have chosen for Arwaand Bao_ Use your model to find the farthest distance that Bao should drive to obtain a 2 pricesaving_ Investigate the relationship between d and 2 p when 2 E is kept constant (eg US$090US$100 hellip etc) Use technology to draw a family of curves for Arwarsquos vehicle Repeatfor Baorsquos vehicle
_ For 2 E _ US$090 provide Arwa with information on three different stations that yieldthis same cost per effective litre Discuss how such information may be useful to Arwa_ For 2 E _ US$100 and 2 p _ US$080 compare the maximum distance that each motoristshould drive and still save moneyArwa is a busy person and wonders whether the saving in money would be worth the time shewould lose in extra driving_ Modify your model to account for the time taken to drive to and from an off-route station

_ Measure these line segments and comment on your results_ Repeat the above for the equations z4 _1 _ 0 and z5 _1 _ 0 Comment on your results andtry to formulate a conjecture_ Factorize zn _1 for n _ 3 4 and 5_ Use graphing software to test your conjecture for some more values of n 1048576 __ and makemodifications to your conjecture if necessary_ Prove your conjecture
Part B
Use de Moivrersquos theorem to obtain solutions to zn _ i for n _ 3 4 and 5_ Use graphing software to represent each of these solutions on an Argand diagram_ Generalize and prove your results for zn _ a _ bi where a _ bi _1
_ What happens when a _ bi _1
THE DICE GAME HL Type IITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo formatThe aim of this task is to create a dice game in a casino and model this usingprobability It is important to examine how best to run the game from both the
perspective of a player and the casino In doing so analyse the game to consider theoptimal payments by the player and payouts by the casino_ Consider a game with two players Ann and Bob Ann has a red die and Bob a white dieThey roll their dice and note the number on the upper face Ann wins if her score is higherthan Bobrsquos (note that Bob wins if the scores are the same) If both players roll their diceonce each what is the probability that Ann will win the game_ Now consider the same game where Ann can roll her die a second time and will note thehigher score of the two rolls but Bob rolls only once In this case what is the probabilitythat Ann will win_ Investigate the game when both players can roll their dice twice and also when bothplayers can roll their dice more than twice but not necessarily the same number of times_ Consider the game in a casino where the player has a red die and the bank has a white dieFind a model for a game so that the casino makes a reasonable profit in the case where theplayer rolls the red die once and the bank rolls the white die once (When creating yourmodel you will need to consider how much a player must pay to play a game and howmuch the bank will pay out if the player wins Do this from the perspective of both theplayer and the casino and consider carefully the criteria for whether the game can be
considered worthwhile for both the player and the casino)_ Now consider other models for the game including cases such as where the player or the
bank rolls their dice multiple times or where multiple players are involved in the game
FILLING UP THE PETROL TANK HL Type IITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo formatIn this task you will develop a mathematical model that helps motorists decide which ofthe following two options is more economicalOption 1 to buy petrol from a station on their normal route at a relatively higher priceOption 2 to drive an extra distance out of their normal route to buy cheaper petrolConsider a situation in which two motorists Arwa and Bao share the same driving route but owndifferent sized vehicles Arwa fills up her vehiclersquos tank at a station along her normal route forUS$ 1 p per litre On the other hand Bao drives an extra d kilometres out of his normal route to fillup his vehiclersquos tank for US$ p2 per litre where p2 _ p1 _ Choose suitable parameters for Arwarsquos and Baorsquos vehicles Justify your choices

_ How can the findings with quadratics and cubics be applied to quartics
PATTERNS FROM COMPLEX NUMBERS HL TYPE ITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo format
Part A
Use de Moivrersquos theorem to obtain solutions to the equation z3 _1 _ 0 _ Use graphing software to plot these roots on an Argand diagram as well as a unit circlewith centre origin_ Choose a root and draw line segments from this root to the other two roots
_ Measure these line segments and comment on your results_ Repeat the above for the equations z4 _1 _ 0 and z5 _1 _ 0 Comment on your results andtry to formulate a conjecture_ Factorize zn _1 for n _ 3 4 and 5_ Use graphing software to test your conjecture for some more values of n 1048576 __ and makemodifications to your conjecture if necessary_ Prove your conjecture
Part B
Use de Moivrersquos theorem to obtain solutions to zn _ i for n _ 3 4 and 5_ Use graphing software to represent each of these solutions on an Argand diagram_ Generalize and prove your results for zn _ a _ bi where a _ bi _1
_ What happens when a _ bi _1
THE DICE GAME HL Type IITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo formatThe aim of this task is to create a dice game in a casino and model this usingprobability It is important to examine how best to run the game from both the
perspective of a player and the casino In doing so analyse the game to consider theoptimal payments by the player and payouts by the casino_ Consider a game with two players Ann and Bob Ann has a red die and Bob a white dieThey roll their dice and note the number on the upper face Ann wins if her score is higherthan Bobrsquos (note that Bob wins if the scores are the same) If both players roll their diceonce each what is the probability that Ann will win the game_ Now consider the same game where Ann can roll her die a second time and will note thehigher score of the two rolls but Bob rolls only once In this case what is the probabilitythat Ann will win_ Investigate the game when both players can roll their dice twice and also when bothplayers can roll their dice more than twice but not necessarily the same number of times_ Consider the game in a casino where the player has a red die and the bank has a white dieFind a model for a game so that the casino makes a reasonable profit in the case where theplayer rolls the red die once and the bank rolls the white die once (When creating yourmodel you will need to consider how much a player must pay to play a game and howmuch the bank will pay out if the player wins Do this from the perspective of both theplayer and the casino and consider carefully the criteria for whether the game can be
considered worthwhile for both the player and the casino)_ Now consider other models for the game including cases such as where the player or the
bank rolls their dice multiple times or where multiple players are involved in the game
FILLING UP THE PETROL TANK HL Type IITo the student The work that you produce to address the questions in this task should be a reportthat can stand on its own It is best to avoid copying the questions in the task to adopt a ldquoquestionand answerrdquo formatIn this task you will develop a mathematical model that helps motorists decide which ofthe following two options is more economicalOption 1 to buy petrol from a station on their normal route at a relatively higher priceOption 2 to drive an extra distance out of their normal route to buy cheaper petrolConsider a situation in which two motorists Arwa and Bao share the same driving route but owndifferent sized vehicles Arwa fills up her vehiclersquos tank at a station along her normal route forUS$ 1 p per litre On the other hand Bao drives an extra d kilometres out of his normal route to fillup his vehiclersquos tank for US$ p2 per litre where p2 _ p1 _ Choose suitable parameters for Arwarsquos and Baorsquos vehicles Justify your choices
_ Suppose 1 p _ US$100 per litre 2 p _ US$098 per litre and d _10 km Which motorist is getting the better deal Show all calculations and justify any assumptions you make_ On a spreadsheet choose several sets of values for 1 p 2 p and d to investigate further_ Define a set of variables that would be relevant in the above situationldquoEffective litresrdquo is a method of comparing the cost of petrol bought under the two optionsdescribed above Effective litres for a given vehicle are those litres used when the vehicle travelsits normal route_ Use your variables and parameters to write algebraic expressions for 1 E and 2 E whichrepresent the cost per effective litre under options 1 and 2 respectively_ Write a model that helps motorists decide on the more economical option for theirvehiclesIn the remainder of this task you need to consider the two vehicles you have chosen for Arwaand Bao_ Use your model to find the farthest distance that Bao should drive to obtain a 2 pricesaving_ Investigate the relationship between d and 2 p when 2 E is kept constant (eg US$090US$100 hellip etc) Use technology to draw a family of curves for Arwarsquos vehicle Repeatfor Baorsquos vehicle
_ For 2 E _ US$090 provide Arwa with information on three different stations that yieldthis same cost per effective litre Discuss how such information may be useful to Arwa_ For 2 E _ US$100 and 2 p _ US$080 compare the maximum distance that each motoristshould drive and still save moneyArwa is a busy person and wonders whether the saving in money would be worth the time shewould lose in extra driving_ Modify your model to account for the time taken to drive to and from an off-route station

Basic Elements of a Good IB Mathematics Portfolio IB Math Internal Assessment (IA) Task HLSL Type 2 Type 1 Project
Correct answers throughout
All questions answered in a logical order
Audience is the teacher
Identify and address the principal goal of the assignment
Written explanations of difficult or less obvious steps in work
Word-processed including use of technology for graphs and equations
Elements of Superior Work
Attention to detail
Consistent use of significant figures or decimal place rounding
Use of proper notation such as ldquoasymprdquo or approximations
Avoid calculator notation such as 45 x^2 or 23E4
Graphs are clear with logical scales and labeled axes
Clearly define all variable that are introduced
Work stands alone
Audience is another student of the same level
Reader doesnrsquot have to refer to the assignment sheet
Reads smoothly and effortlessly
Answers are not numbered unless required
Single word-processed document
Integrate an equation-writing program spreadsheets graphing program etc
Comment on everything included
Explain all steps each time a new mathematical process is used
Avoid repetition of processes already explained
Graphs charts etc appear on the same page where they are explained
Student goes beyond the assignment with insight and sophistication
Identify and address the hidden goals of the assignment
Try to get into the mind of the writer of the assignment
Most tasks leave some space for the top students to explore
Student uses a variety of mathematical approaches
A good assignment will require the use of many kinds of math
A good question will often have several possible approaches for the solution
All math used is relevant to the task
No fluff or space-fillers
Tips to the Students
Work through all problems with pencil and calculator before writing it up
Gives an overall feel for the project so that that student can start to address the main goal and
even insights right from the start
Write a brief introduction rather than jumping right in to the first question
Sets a tone of readability
Math SLHL students can pretend that they are writing a chapter in a textbook
Encourages students to fully explain each step remembering that their audience is another
student from their course of average ability
Students can have fun with creative formatting
Take pride in the look and feel of their work
Math Studies students can approach the IA Project as they would a science lab
Write a hypothesis
Collect data
Analyze data
Draw conclusions
Discuss possible errors or improvements
Common Problems
Solutions to individual problems are cut in half by the page break
It is ok to leave space on the bottom of a page
Use the ldquoInsert Page-Breakrdquo feature of most word-processing programs when a new problem is
started (If there is not enough space on the current page)
Proof for comments like ldquosee the graph belowrdquo when the graph was accidentally bumped to the
next page during editing
Pages of graphs or charts with comments and explanations at end
Full-page graphs should be avoided if possible
Include small (but clear) graphs with an explanation on the same page
Use features like ldquotext-wrappingrdquo to make graphs or charts look and feel like an integrated part
of the work
If a graph must take up a full page include a full discussion of it on the next page
Pages of raw data in the main body of text
Raw data should be organized as concisely as possible and included in the appendix
The main body should only include the compiled data used in the relevant calculation
Frequent reference to appendix
Cuts the flow of the work
If what is in the appendix is very important move it to the body
Over-researching
IB Math Internal Assessments are not research projects
IB is looking for student work and it is obvious when it is not
Grading
Read paper from start to finish before assigning grades
Detail is important
Overall feel is important
Make comments or corrections in the text
Comments help the IB moderator to understand how you have assigned marks
Reference the IB Rubric on a regular basis
IB has two rubrics which could be used for students at many levels

perspective of a player and the casino In doing so analyse the game to consider theoptimal payments by the player and payouts by the casino_ Consider a game with two players Ann and Bob Ann has a red die and Bob a white dieThey roll their dice and note the number on the upper face Ann wins if her score is higherthan Bobrsquos (note that Bob wins if the scores are the same) If both players roll their diceonce each what is the probability that Ann will win the game_ Now consider the same game where Ann can roll her die a second time and will note thehigher score of the two rolls but Bob rolls only once In this case what is the probabilitythat Ann will win_ Investigate the game when both players can roll their dice twice and also when bothplayers can roll their dice more than twice but not necessarily the same number of times_ Consider the game in a casino where the player has a red die and the bank has a white dieFind a model for a game so that the casino makes a reasonable profit in the case where theplayer rolls the red die once and the bank rolls the white die once (When creating yourmodel you will need to consider how much a player must pay to play a game and howmuch the bank will pay out if the player wins Do this from the perspective of both theplayer and the casino and consider carefully the criteria for whether the game can be
considered worthwhile for both the player and the casino)_ Now consider other models for the game including cases such as where the player or the
bank rolls their dice multiple times or where multiple players are involved in the game

Basic Elements of a Good IB Mathematics Portfolio IB Math Internal Assessment (IA) Task HLSL Type 2 Type 1 Project
Correct answers throughout
All questions answered in a logical order
Audience is the teacher
Identify and address the principal goal of the assignment
Written explanations of difficult or less obvious steps in work
Word-processed including use of technology for graphs and equations
Elements of Superior Work
Attention to detail
Consistent use of significant figures or decimal place rounding
Use of proper notation such as ldquoasymprdquo or approximations
Avoid calculator notation such as 45 x^2 or 23E4
Graphs are clear with logical scales and labeled axes
Clearly define all variable that are introduced
Work stands alone
Audience is another student of the same level
Reader doesnrsquot have to refer to the assignment sheet
Reads smoothly and effortlessly
Answers are not numbered unless required
Single word-processed document
Integrate an equation-writing program spreadsheets graphing program etc
Comment on everything included
Explain all steps each time a new mathematical process is used
Avoid repetition of processes already explained
Graphs charts etc appear on the same page where they are explained
Student goes beyond the assignment with insight and sophistication
Identify and address the hidden goals of the assignment
Try to get into the mind of the writer of the assignment
Most tasks leave some space for the top students to explore
Student uses a variety of mathematical approaches
A good assignment will require the use of many kinds of math
A good question will often have several possible approaches for the solution
All math used is relevant to the task
No fluff or space-fillers
Tips to the Students
Work through all problems with pencil and calculator before writing it up
Gives an overall feel for the project so that that student can start to address the main goal and
even insights right from the start
Write a brief introduction rather than jumping right in to the first question
Sets a tone of readability
Math SLHL students can pretend that they are writing a chapter in a textbook
Encourages students to fully explain each step remembering that their audience is another
student from their course of average ability
Students can have fun with creative formatting
Take pride in the look and feel of their work
Math Studies students can approach the IA Project as they would a science lab
Write a hypothesis
Collect data
Analyze data
Draw conclusions
Discuss possible errors or improvements
Common Problems
Solutions to individual problems are cut in half by the page break
It is ok to leave space on the bottom of a page
Use the ldquoInsert Page-Breakrdquo feature of most word-processing programs when a new problem is
started (If there is not enough space on the current page)
Proof for comments like ldquosee the graph belowrdquo when the graph was accidentally bumped to the
next page during editing
Pages of graphs or charts with comments and explanations at end
Full-page graphs should be avoided if possible
Include small (but clear) graphs with an explanation on the same page
Use features like ldquotext-wrappingrdquo to make graphs or charts look and feel like an integrated part
of the work
If a graph must take up a full page include a full discussion of it on the next page
Pages of raw data in the main body of text
Raw data should be organized as concisely as possible and included in the appendix
The main body should only include the compiled data used in the relevant calculation
Frequent reference to appendix
Cuts the flow of the work
If what is in the appendix is very important move it to the body
Over-researching
IB Math Internal Assessments are not research projects
IB is looking for student work and it is obvious when it is not
Grading
Read paper from start to finish before assigning grades
Detail is important
Overall feel is important
Make comments or corrections in the text
Comments help the IB moderator to understand how you have assigned marks
Reference the IB Rubric on a regular basis
IB has two rubrics which could be used for students at many levels
Math Studies (Open-ended project)

Written explanations of difficult or less obvious steps in work
Word-processed including use of technology for graphs and equations
Elements of Superior Work
Attention to detail
Consistent use of significant figures or decimal place rounding
Use of proper notation such as ldquoasymprdquo or approximations
Avoid calculator notation such as 45 x^2 or 23E4
Graphs are clear with logical scales and labeled axes
Clearly define all variable that are introduced
Work stands alone
Audience is another student of the same level
Reader doesnrsquot have to refer to the assignment sheet
Reads smoothly and effortlessly
Answers are not numbered unless required
Single word-processed document
Integrate an equation-writing program spreadsheets graphing program etc
Comment on everything included
Explain all steps each time a new mathematical process is used
Avoid repetition of processes already explained
Graphs charts etc appear on the same page where they are explained
Student goes beyond the assignment with insight and sophistication
Identify and address the hidden goals of the assignment
Try to get into the mind of the writer of the assignment
Most tasks leave some space for the top students to explore
Student uses a variety of mathematical approaches
A good assignment will require the use of many kinds of math
A good question will often have several possible approaches for the solution
All math used is relevant to the task
No fluff or space-fillers
Tips to the Students
Work through all problems with pencil and calculator before writing it up
Gives an overall feel for the project so that that student can start to address the main goal and
even insights right from the start
Write a brief introduction rather than jumping right in to the first question
Sets a tone of readability
Math SLHL students can pretend that they are writing a chapter in a textbook
Encourages students to fully explain each step remembering that their audience is another
student from their course of average ability
Students can have fun with creative formatting
Take pride in the look and feel of their work
Math Studies students can approach the IA Project as they would a science lab
Write a hypothesis
Collect data
Analyze data
Draw conclusions
Discuss possible errors or improvements
Common Problems
Solutions to individual problems are cut in half by the page break
It is ok to leave space on the bottom of a page
Use the ldquoInsert Page-Breakrdquo feature of most word-processing programs when a new problem is
started (If there is not enough space on the current page)
Proof for comments like ldquosee the graph belowrdquo when the graph was accidentally bumped to the
next page during editing
Pages of graphs or charts with comments and explanations at end
Full-page graphs should be avoided if possible
Include small (but clear) graphs with an explanation on the same page
Use features like ldquotext-wrappingrdquo to make graphs or charts look and feel like an integrated part
of the work
If a graph must take up a full page include a full discussion of it on the next page
Pages of raw data in the main body of text
Raw data should be organized as concisely as possible and included in the appendix
The main body should only include the compiled data used in the relevant calculation
Frequent reference to appendix
Cuts the flow of the work
If what is in the appendix is very important move it to the body
Over-researching
IB Math Internal Assessments are not research projects
IB is looking for student work and it is obvious when it is not
Grading
Read paper from start to finish before assigning grades
Detail is important
Overall feel is important
Make comments or corrections in the text
Comments help the IB moderator to understand how you have assigned marks
Reference the IB Rubric on a regular basis
IB has two rubrics which could be used for students at many levels

started (If there is not enough space on the current page)
Proof for comments like ldquosee the graph belowrdquo when the graph was accidentally bumped to the
next page during editing
Pages of graphs or charts with comments and explanations at end
Full-page graphs should be avoided if possible
Include small (but clear) graphs with an explanation on the same page
Use features like ldquotext-wrappingrdquo to make graphs or charts look and feel like an integrated part
of the work
If a graph must take up a full page include a full discussion of it on the next page
Pages of raw data in the main body of text
Raw data should be organized as concisely as possible and included in the appendix
The main body should only include the compiled data used in the relevant calculation
Frequent reference to appendix
Cuts the flow of the work
If what is in the appendix is very important move it to the body
Over-researching

Basic Elements of a Good IB Mathematics Portfolio IB Math Internal Assessment (IA) Task HLSL Type 2 Type 1 Project
Correct answers throughout
All questions answered in a logical order
Audience is the teacher
Identify and address the principal goal of the assignment
Written explanations of difficult or less obvious steps in work
Word-processed including use of technology for graphs and equations
Elements of Superior Work
Attention to detail
Consistent use of significant figures or decimal place rounding
Use of proper notation such as ldquoasymprdquo or approximations
Avoid calculator notation such as 45 x^2 or 23E4
Graphs are clear with logical scales and labeled axes
Clearly define all variable that are introduced
Work stands alone
Audience is another student of the same level
Reader doesnrsquot have to refer to the assignment sheet
Reads smoothly and effortlessly
Answers are not numbered unless required
Single word-processed document
Integrate an equation-writing program spreadsheets graphing program etc
Comment on everything included
Explain all steps each time a new mathematical process is used
Avoid repetition of processes already explained
Graphs charts etc appear on the same page where they are explained
Student goes beyond the assignment with insight and sophistication
Identify and address the hidden goals of the assignment
Try to get into the mind of the writer of the assignment
Most tasks leave some space for the top students to explore
Student uses a variety of mathematical approaches
A good assignment will require the use of many kinds of math
A good question will often have several possible approaches for the solution
All math used is relevant to the task
No fluff or space-fillers
Tips to the Students
Work through all problems with pencil and calculator before writing it up
Gives an overall feel for the project so that that student can start to address the main goal and
even insights right from the start
Write a brief introduction rather than jumping right in to the first question
Sets a tone of readability
Math SLHL students can pretend that they are writing a chapter in a textbook
Encourages students to fully explain each step remembering that their audience is another
student from their course of average ability
Students can have fun with creative formatting
Take pride in the look and feel of their work
Math Studies students can approach the IA Project as they would a science lab
Write a hypothesis
Collect data
Analyze data
Draw conclusions
Discuss possible errors or improvements
Common Problems
Solutions to individual problems are cut in half by the page break
It is ok to leave space on the bottom of a page
Use the ldquoInsert Page-Breakrdquo feature of most word-processing programs when a new problem is
started (If there is not enough space on the current page)
Proof for comments like ldquosee the graph belowrdquo when the graph was accidentally bumped to the
next page during editing
Pages of graphs or charts with comments and explanations at end
Full-page graphs should be avoided if possible
Include small (but clear) graphs with an explanation on the same page
Use features like ldquotext-wrappingrdquo to make graphs or charts look and feel like an integrated part
of the work
If a graph must take up a full page include a full discussion of it on the next page
Pages of raw data in the main body of text
Raw data should be organized as concisely as possible and included in the appendix
The main body should only include the compiled data used in the relevant calculation
Frequent reference to appendix
Cuts the flow of the work
If what is in the appendix is very important move it to the body
