Python Math: Functions in Python Math Module
In-Built methods of math module:
This module provides the different types of mathematical functions to perform the mathematical operation. This function does not support complex number problems. To solve the complex number problem cmath module is used. There are lots of functions present in this module and all are discussed below:
