Introduction to Python Math Functions

Math functions in Python allow you to perform various mathematical operations. Python comes with a built-in math module that provides a wide range of mathematical functions and constants. In this tutorial, we will cover some essential math functions, including addition, subtraction, multiplication, division, exponentiation, and more.

Importing the math Module

To use Python’s math functions, you need to import the math module. Here’s how you can do it:

import math

Basic Math Operations

1. Addition and Subtraction

Let’s start with the basics: addition and subtraction.

# Addition
result_add = 5 + 3
print("Addition:", result_add)

# Subtraction
result_sub = 8 - 2
print("Subtraction:", result_sub)


Addition: 8
Subtraction: 6

2. Multiplication and Division

Next, we have multiplication and division:

# Multiplication
result_mul = 6 * 4
print("Multiplication:", result_mul)

# Division
result_div = 10 / 2
print("Division:", result_div)


Multiplication: 24
Division: 5.0

3. Exponentiation

You can also perform exponentiation using the ** operator:

# Exponentiation
result_exp = 2 ** 3
print("Exponentiation:", result_exp)


Exponentiation: 8

Using the math Module

Now, let’s explore some advanced math functions provided by the math module.

4. Square Root

To calculate the square root of a number, use the math.sqrt() function:

import math

number = 25
result_sqrt = math.sqrt(number)
print("Square Root of", number, "is:", result_sqrt)


Square Root of 25 is: 5.0

5. Trigonometric Functions

Python’s math module also includes trigonometric functions such as sin(), cos(), and tan(). Here’s an example using the sin() function:

import math

angle_degrees = 45
angle_radians = math.radians(angle_degrees)
result_sin = math.sin(angle_radians)
print("Sine of", angle_degrees, "degrees is:", result_sin)


Sine of 45 degrees is: 0.7071067811865475

6. Constants

The math module provides useful mathematical constants, like pi and e:

import math

pi_value = math.pi
e_value = math.e

print("Value of pi:", pi_value)
print("Value of e:", e_value)


Value of pi: 3.141592653589793
Value of e: 2.718281828459045
