4 Python Math

1. What is the Math Module?

Python has a built-in module called math.

In simple words:
👉 The math module helps us do mathematical work easily
👉 It gives ready-made functions for numbers

Examples:

• Square root

• Power

• Rounding

• Trigonometry

2. Import Math Module

Before using math functions, we must import it.

Example

3. Square Root (sqrt())

Example

Output:

4. Power of a Number (pow())

Example

Output:

 

5. Round Numbers

ceil() – Round UP

Output:

floor() – Round DOWN

Output:

6. Absolute Value (abs())

Removes minus sign.

Example

Output:

7. Find Maximum and Minimum

Example

8. Value of Pi (pi)

Example

Output:

9. Value of Euler’s Number (e)

Example

10. Trigonometry Functions

Angles are in radians, not degrees.

Example

11. Factorial (factorial())

Example

Output:

12. Logarithm (log())

Example

13. Check if Number is Finite

Example

14. Common Beginner Mistakes
