Math

math module

The math module can be imported with the statement import math.

The math module is used to do math. To do statistics, use the statistics module.

Functions

• math.sqrt(number): calculates the square root of a number n. $n \in \mathbb{R}_+$
• math.isqrt(number): calculates the integer square root of a number n. $n \in \mathbb{N}$
• math.root(number, k): calculates the k root of a number n. $n \in \mathbb{R}_+, k \in \mathbb{R}$
• math.iroot(number, k): calculates the k root of a number n. $n \in \mathbb{R}_+, k \in \mathbb{R}$
• math.degrees(angle): transform a radian angle to a degree angle. $angle \in \mathbb{R}$
• math.radians(angle): transform a degree angle to a radian angle. $angle \in \mathbb{R}$
• math.sin(angle): calculates sine of an angle in radians. $angle \in \mathbb{R}$
• math.cos(angle): calculates cosine of an angle in radians. $angle \in \mathbb{R}$
