The math module¶

The math module contains the kinds of mathematical functions you would typically find on your calculator and some mathematical constants like pi and e.

Here are some items from the math module in action.

If you want more information, you can check out the Math Module Python Documentation.

import math

print(math.pi)
print(math.e)

print(math.sqrt(2.0))

print(math.sin(math.radians(90)))   # sin of 90 degrees

(chmodule_02)

Like almost all other programming languages, angles are expressed in radians rather than degrees. There are two functions radians and degrees to convert between the two popular ways of measuring angles.

Notice another difference between this module and our use of turtle.
In turtle we create objects (either Turtle or Screen) and call methods on those objects (recall alex and tess).
Mathematical functions do not need to be constructed.
They simply perform a task.
