Python Math

Python provides a built-in math module that contains many useful mathematical functions and constants. These functions can be used to perform mathematical operations such as trigonometry, logarithms, and rounding.

Importing the Math Module

Before you can use the functions in the math module, you need to import it using theimport keyword:

import math

Basic Math Functions

The math module provides functions for basic mathematical operations, such assqrt() for square root, pow() for exponentiation, abs() for absolute value, and round() for rounding:

import math

print(math.sqrt(16))  # Output: 4.0
print(math.pow(2, 3))  # Output: 8.0
print(math.abs(-5))   # Output: 5
print(math.round(3.14159, 2))  # Output: 3.14

Trigonometric Functions

The math module also provides trigonometric functions, such as sin(),cos(), and tan(), which accept angles in radians:

import math

angle = math.radians(45)
print(math.sin(angle))  # Output: 0.7071067811865476
print(math.cos(angle))  # Output: 0.7071067811865475
print(math.tan(angle))  # Output: 1.0

Constants

The math module also provides constants such as pi and e:

import math

print(math.pi)  # Output: 3.141592653589793
print(math.e)   # Output: 2.718281828459045

Conclusion

The math module in Python provides a wide range of mathematical functions and constants that can be used to perform complex mathematical operations. By understanding how to use the mathmodule, you can perform a variety of mathematical tasks in your Python programs.
