Simple programming

Simple programming for your

TI calculator

The four things you want your

program to do: • Prompt - to ask you for something

• Calculate and store – perform whatever

operations need to be done on that

something, and put it somewhere

• Display – to tell you what was the result of

those calculations on those somethings

Let’s start simple:

• We’ll program the

calculator to find the

circumference of a

circle:

Let’s start simple:

• We’ll program the

circumference of a

circle:

• First click PRGM:

• Cursor to NEW:

• Enter:

Let’s start simple:

• Notice the cursor is a

letter A, which means

it’s in alpha mode.

Let’s start simple:

• Notice the cursor is a

letter A, which means

it’s in alpha mode.

• The calculator is

waiting for you to type

in the name of the

program...call it

CIRCMFNC

CIRCMFNC

• enter

Let’s start simple:

• Click PRGM again

• This time you see a

different menu than

the last time you

clicked PRGM:

Let’s start simple:

• Click PRGM again

• This time you see a

different menu than

the last time you

clicked PRGM:

• Cursor to I/O

Let’s start simple:

• Click PRGM again

• This time you see a

different menu than

the last time you

clicked PRGM:

• Cursor to I/O

• Select Prompt, hit

enter:

Let’s start simple:

• Now the calc is

waiting for you to tell

it what to prompt for

Let’s start simple:

• Now the calc is

waiting for you to tell

it what to prompt for

• You have to get back

into alpha mode

before you answer

Let’s start simple:

• Now the calc is

waiting for you to tell

it what to prompt for

• You have to get back

into alpha mode

before you answer

• So press ALPHA,

then type R, then

enter:

Let’s start simple:

• Now we have to give

the program a formula

to calculate

circumference, so

type in 2R

Let’s start simple:

• Now we have to give

the program a formula

to calculate

circumference, so

type in 2R

• Then STO>

• Then alpha C, then

enter

Let’s start simple:

• Now we have to give

the program a formula

to calculate

circumference, so

type in 2R

• Then STO>

• Then alpha C, then

enter

You just asked the

calculator to

perform the

calculation and

call the answer C!

Let’s start simple:

• Now we have to ask

the calculator to

display the result of

the calculation

Let’s start simple:

• Click PRGM again,

cursor to I/O as

before, and this time

select DISP

Let’s start simple:

• Click PRGM again,

cursor to I/O as

before, and this time

select DISP, then

enter

Let’s start simple:

• Click PRGM again,

cursor to I/O as

before, and this time

select DISP, then

enter

• Click 2ND ALPHA to

lock into alpha mode

Let’s start simple:

• Click PRGM again,

cursor to I/O as

before, and this time

select DISP and enter

to get this:

• Click 2ND ALPHA to

lock into alpha mode

• Type “C EQUALS”, C

then enter

Now let’s execute the program:

• Click 2ND QUIT to exit

this mode

Now let’s execute the program:

• Click 2ND QUIT to exit

this mode

• PRGM

Now let’s execute the program:

• Click 2ND QUIT to exit

this mode

• PRGM

• Enter:

Now let’s execute the program:

• Click 2ND QUIT to exit

this mode

• PRGM

• Enter:

• Enter:

Now let’s execute the program:

• Click 2ND QUIT to exit

this mode

• PRGM

• Enter:

• Enter:

Prompting you

for R, just like

you told it to

Now let’s execute the program:

• Click 2ND QUIT to exit

this mode

• PRGM

• Enter:

• Enter:

• Type 10 then enter:

Now let’s execute the program:

• Click 2ND QUIT to exit

this mode

• PRGM

• Enter:

• Enter:

• Type 10 then enter:

Displaying what

you told it to

display!

Now let’s execute the program:

• Click 2ND QUIT to exit

this mode

• PRGM

• Enter:

• Enter:

• Type 10 then enter:

Calculated 2r

and now

displaying the

result!
