python math

Python math module provides mathematical functions and constants, which can be directly used in Python code. Some of the commonly used functions and constants are:

Functions:

- `abs(x)`: Returns the absolute value of x.
- `pow(x, y)`: Returns x raised to the power of y.
- `sqrt(x)`: Returns the square root of x.
- `exp(x)`: Returns the exponential value of x.
- `log(x)`: Returns the natural logarithm of x.
- `sin(x)`: Returns the sine value of x.
- `cos(x)`: Returns the cosine value of x.
- `tan(x)`: Returns the tangent value of x.
- `asin(x)`: Returns the inverse sine value of x.
- `acos(x)`: Returns the inverse cosine value of x.
- `atan(x)`: Returns the inverse tangent value of x.

Constants:

- `pi`: Returns the value of pi (3.141592653589793).
- `e`: Returns the value of Euler's number (2.718281828459045).

Example usage:

import math

# absolute value
print(abs(-4.5))  # output: 4.5

# power
print(pow(2, 3))  # output: 8

# square root
print(math.sqrt(16))  # output: 4.0

# exponential
print(math.exp(2))  # output: 7.3890560989306495

# natural logarithm
print(math.log(10))  # output: 2.302585092994046

# trigonometric functions
print(math.sin(math.pi/2))  # output: 1.0
print(math.cos(math.pi))  # output: -1.0
print(math.tan(math.pi/4))  # output: 0.9999999999999999

# inverse trigonometric functions
print(math.asin(1))  # output: 1.5707963267948966
print(math.acos(0.5))  # output: 1.0471975511965979
print(math.atan(1))  # output: 0.7853981633974483

# constants
print(math.pi)  # output: 3.141592653589793
print(math.e)  # output: 2.718281828459045
