Python Math
Python has a built-in math module that gives access to many mathematical functions like square roots, trigonometry, logarithms, rounding, and more.
🔹 Importing the Math Module
Before using math functions, you need to import the module:
import math
🔹 Common Math Functions
| Function | Description |
|---|---|
math.sqrt(x) |
Square root of x |
math.pow(x, y) |
x raised to the power y |
math.floor(x) |
Rounds down to nearest integer |
math.ceil(x) |
Rounds up to nearest integer |
math.pi |
Returns the value of π (3.14159) |
math.e |
Euler's number (2.718...) |
math.fabs(x) |
Absolute value (float) |
math.factorial(x) |
Factorial of x |
🔹 Example: Square Root
import math
print(math.sqrt(16)) # Output: 4.0
🔹 Example: Power
print(math.pow(2, 3)) # Output: 8.0
🔹 Example: Rounding
print(math.floor(3.7)) # Output: 3
print(math.ceil(3.2)) # Output: 4
🔹 Example: Factorial
print(math.factorial(5)) # Output: 120
🔹 Trigonometric Functions
| Function | Description |
|---|---|
math.sin(x) |
Sine of x (in radians) |
math.cos(x) |
Cosine of x (in radians) |
math.tan(x) |
Tangent of x (in radians) |
math.radians(x) |
Converts degrees to radians |
math.degrees(x) |
Converts radians to degrees |
🔹 Example: Trigonometry
angle = math.radians(90)
print(math.sin(angle)) # Output: 1.0
