`math`

The Python math module provides a comprehensive collection of mathematical functions and constants, making it a go-to tool for performing mathematical operations in Python. It includes functions for trigonometry, logarithms, powers, and other common mathematical calculations.

Here’s a quick example:

Python
      
>>> import math
>>> math.sqrt(16)
4.0

Key Features

Provides mathematical constants, such as π (pi) and e
Offers a range of functions for trigonometry, logarithms, and more
Supports operations for floating-point numbers

Frequently Used Classes and Functions

Object	Type	Description
`math.pi`	Constant	The mathematical constant π
`math.e`	Constant	The base of natural logarithms, e
`math.sqrt()`	Function	Computes the square root of a number
`math.sin()`	Function	Computes the sine of a number (radians)
`math.cos()`	Function	Computes the cosine of a number (radians)
`math.log()`	Function	Computes the natural logarithm (base e)

Examples

Calculate the sine of π/2:

Python
      
>>> import math

>>> math.sin(math.pi / 2)
1.0

Compute the logarithm of 10:

Python
      
>>> math.log(10)
2.302585092994046

Find the square root of 25:

Python
      
>>> math.sqrt(25)
5.0

Common Use Cases

Performing trigonometric calculations for scientific and engineering applications
Calculating logarithms and exponentials for data analysis
Using mathematical constants in formulas

Real-World Example

Imagine you’re working on a physics simulation and need to calculate the trajectory of a projectile. The math module can help compute the necessary trigonometric values to determine its path:

Python
      
        
      
    
>>> import math
>>> velocity = 20  # m/s
>>> angle = 45  # degrees
>>> angle_rad = math.radians(angle)
>>> horizontal_velocity = velocity * math.cos(angle_rad)
>>> vertical_velocity = velocity * math.sin(angle_rad)
>>> horizontal_velocity
14.142135623730951
>>> vertical_velocity
14.14213562373095

In this example, the math module is used to convert degrees to radians and compute the horizontal and vertical components of the velocity, demonstrating its utility in physics calculations.
