Python has a built-in math module that provides a set of functions for mathematical operations. Here are some commonly used math methods in Python:

abs(): Returns the absolute value of a number.

ceil(): Returns the smallest integer greater than or equal to a number.

floor(): Returns the largest integer less than or equal to a number.

round(): Returns the nearest integer to a number.

sqrt(): Returns the square root of a number.

pow(): Returns the value of a number raised to a specified power.

log(): Returns the natural logarithm of a number.

log10(): Returns the base-10 logarithm of a number.

exp(): Returns the value of e raised to the power of a specified number.

cos(): Returns the cosine of a number in radians.

sin(): Returns the sine of a number in radians.

tan(): Returns the tangent of a number in radians.

acos(): Returns the inverse cosine of a number in radians.

asin(): Returns the inverse sine of a number in radians.

atan(): Returns the inverse tangent of a number in radians.

Here's an example of using some of these methods:
