In order to perform mathematical functions, python has a built-in module `math`

with all the mathematical functions. To use this module Some of the functions are:
Factorial of a number = **factorial(number)**
To find the absolute value of a number = **fabs(number)**
To find the square root of a number = **sqrt(number)**
To use these functions the `math`

module has to be imported using the statement `import math`

. This is illustrated in the example below.

In the below example we find the factorial of 5, the absolute value of -5.345, square root of 49.

It supports all the trigonometric functions like **sin, cos, tan, tanh, sinh, cosh**, and so on.
In this example, we are finding the sin, oos, tan, tanh, sinh, cosh of 90

`math`

module also has mathematical constants like `pi`

, `e`

, and so on.
In this example, we are printing the values of `pi`

and `e`

.

**Along with these functions the math module consists of all the logarithimic functions, angle conversion functions and representation functions**
