Python Math Module
The math
module in Python provides access to a variety of mathematical functions, enabling you to perform complex mathematical calculations with ease. These functions include operations like square roots, factorials, logarithms, trigonometry, and more.
Commonly Used Functions
The math
module offers a wide range of functions. Below are some of the most commonly used functions:
sqrt(x)
: Returns the square root ofx
.factorial(x)
: Returns the factorial ofx
. This is the product of all positive integers less than or equal tox
.pow(x, y)
: Returnsx
raised to the power ofy
. Equivalent tox**y
.log(x, base)
: Returns the logarithm ofx
to the specified base. If the base is not provided, it returns the natural logarithm (basee
).sin(x)
,cos(x)
,tan(x)
: Returns the sine, cosine, or tangent ofx
(wherex
is in radians).degrees(x)
,radians(x)
: Converts angles between degrees and radians.
Example Usage
Below are some examples demonstrating how to use the functions from the math
module:
import math
# Calculate the square root of 16
print(math.sqrt(16)) # Output: 4.0
# Calculate the factorial of 5
print(math.factorial(5)) # Output: 120
# Calculate 2 raised to the power of 3
print(math.pow(2, 3)) # Output: 8.0
# Calculate the logarithm of 100 with base 10
print(math.log(100, 10)) # Output: 2.0
# Calculate the sine of 90 degrees (converted to radians)
print(math.sin(math.radians(90))) # Output: 1.0
