This document describes a math library containing pre-defined functions for mathematical operations, which are included in the <cmath> header file. Key functions highlighted include sqrt for square roots, pow for exponentiation, and sin/cos for trigonometric calculations. Each function takes specific arguments and returns results as double values, with examples provided for clarity.

Prepared by : Omar A. Fernandez, MSIT

2. Pre-defined Math Functions
• provides a math library that contains a set of pre-defined
mathematical functions.
• functions are included in the <cmath> header file
• allow you to perform various mathematical operations, such as
calculating square roots, raising numbers to power, and evaluating
trigonometric functions.

3. Math Library Functions
• sqrt
The sqrt function is used to calculate the square root of a number. It takes a
single argument and returns the square root as a double value.

4. Math Library Functions
Here's an example:

5. Math Library Functions
Here’s the output:

6. Math Library Functions
• Pow
The pow function is used to raise a number to a power.
It takes two arguments: the base number and the exponent. It returns the
result as a double value.

7. Math Library Functions
Here's an example:

8. Math Library Functions
Here’s the output: The output will be: "2.00 raised to the power of 3.00 is 8.00".

9. Math Library Functions
• Sin and cos
The sin and cos functions are used to calculate the sine and cosine of an angle,
respectively.
These functions take the angle in radians as an argument and return the
corresponding sine or cosine value as a double value.

10. Math Library Functions
Here's an example:

11. Math Library Functions
Here’s the output: The output will be: "Sine of 0.50 is 0.48" "Cosine of 0.50 is
0.88".
