Math module in python

Introduction

Python is a popular programming language used in a wide range of applications. One of the key strengths of Python is its extensive library of modules, which can be used to accomplish a wide range of tasks. In this post, we will explore the math module in Python, which provides access to a range of mathematical functions.

Getting started with the math module

To use the math module, we first need to import it into our Python program using the following statement:

import math

Once we have imported the math module, we can use its functions in our program.

Basic mathematical functions

The math module provides a wide range of mathematical functions, including basic arithmetic functions such as roundings, abs, factorials, and sqrt. Here are a few examples:

import math

# floor function
result = math.floor(3.14159)
print(result)  # Output: 3

# Absolute value function
result = math.fabs(-10)
print(result)  # Output: 10

# Factorial function
result = math.factorial(5)
print(result)  # Output: 120

Trigonometric functions

The math module also provides a range of trigonometric functions, which can be used to calculate angles and distances. Here are a few examples:

import math


# Sine function
result = math.sin(math.pi / 2)
print(result)  # Output: 1.0


# Cosine function
result = math.cos(math.pi / 4)
print(result)  # Output: 0.7071067811865476


# Tangent function
result = math.tan(math.pi / 4)
print(result)  # Output: 0.9999999999999999

Exponential and logarithmic functions

The math module also provides a range of exponential and logarithmic functions, which can be used to calculate powers and logarithms. Here are a few examples:

import math


# Exponential function
result = math.exp(2)
print(result)  # Output: 7.3890560989306495


# Logarithmic function
result = math.log10(100)
print(result)  # Output: 2.0

Constants

The Math Module provides several useful mathematical constants, such as:

import math
print(math.pi)      # The value of Pi
print(math.e)       # The value of Euler's number
print(math.inf)     # Infinity
print(math.nan)     # Not a Number

Conclusion

The math module is a powerful tool for performing mathematical operations in Python. It provides a range of functions for basic arithmetic, trigonometry, exponential and logarithmic functions, rounding, absolute values, and factorials. By mastering the math module, you can perform complex mathematical operations with ease and precision. In the next part of this blog, we will explore some more advanced features of the math module.
