python math库

The math module in Python provides various mathematical functions and constants. Some of the functions and constants provided by the math module are:

1. Trigonometric functions: sin(), cos(), tan(), asin(), acos(), atan()

2. Exponential and logarithmic functions: exp(), log(), log10()

3. Power and square root functions: pow(), sqrt()

4. Constants: pi, e

Example:

import math

# Finding the square root of a number
print(math.sqrt(25)) # Output: 5.0

# Finding the value of pi
print(math.pi) # Output: 3.141592653589793

# Finding the sine of an angle
print(math.sin(math.pi/2)) # Output: 1.0

# Finding the exponential value of a number
print(math.exp(3)) # Output: 20.085536923187668

Note: The math module is part of the standard Python library and does not require any additional installation.
