SCIENTIFIC CALCULATOR

A scientific calculatoris a type of electronic calculator, usually but not always handheld,

designed to calculate problems in science (especially physics), engineering, and mathematics.

In certain contexts such as higher education, scientific calculators have been superseded by

graphing calculators, which offer a superset of scientific calculator functionality along with the

ability to graph input data and write and store programs for the device. There is also some

overlap with the financial calculator market.

Functions:-

Modern scientific calculators generally have many more features than a standard four or five-

function calculator, and the feature set differs between manufacturers and models; however, the

defining features of a scientific calculator include:

Scientific notation for calculating large numbers

Floating point arithmetic

Logarithmic functions, using both base 10 and base e

trigonometry functions

exponents and roots beyond the square roots

quick access to constants such as pi and e

In addition, high-end scientific calculators include:

hexadecimal, binary, and octal calculations, including basic Boolean math

complex numbers

fractions

statistics and probability calculations

programmability

equation solving

While most scientific models have traditionally used a single-line display similar to traditional

pocket calculators, many of them have at the very least many digits (10 to 12), sometimes with

extra digits for the floating point exponent.

A few have multi-line displays, with some recent models from Test

instruments and Casio using Dot matrix displays similar to those found on graphing calculators.

Uses:-

1. Scientific calculators are used widely in any situation where quick access to certain

mathematical functions is needed, especially those such as trigonometric functions that were

once traditionally looked up in tables and some aspects of astronomy, physics, and chemistry.

2. They are very often required for math classes from the junior high school level through

college.

3. These are generally either permitted or required on many standardized tests covering

math and science subjects.

Here is the snapshot of Scientific Calculator which I had made While I Started Making This

Introduction:-

This is a scientific calculator involving many functions such as:

1. Normal arithmetic operations.

2. Functions such as factorial, permutation, combination etc.

3. Scientific functions (sin, cos, sin-1

, cos-1

, etc.).4. Operations on complex numbers.

5. Storage of values in variables and operations on these variables.

6. Evaluation of simple series.

7. Expressions involving any combination of the above.

Some Special Features

1. Easy-to-use interface

The calculator provides an easy-to-use interface. The expressions can be entered easily using the

keyboard or by clicking the buttons using the mouse.

2. Display of evaluated value in fraction form

Values of expressions can be viewed in normal decimal form or in the fraction form. Default is

the decimal form.

3. Angle measurements

We can do Angle measurements in degree, radian, or grade.

4. Variables

The calculator provides 9 memory variables.

Values can be stored in these variables.

The value can be that of real numbers or complex numbers.

How to use:-

1. Just open the scientific calculator

1. Enter any expression.

2. Press calculate button on the calculator.

3. If the answer is lengthy scroll down the textbox to view the complete answer.

This calculator will work like other calculators but there is something extra than the normal

calculator. As it is scientific calculator so I had added the following functions to calculate or

solve the complex mathematical expressions:-

1. Sin function

2. Cos function

Page7

3. Tan function

4. Absolute function

5. Square root function

These functions will work accordingly to their inputs and will display the result when we press

that particular function button or calculate button. Actually this project is under construction, so I

havent mentioned and used all the functions there.
