In this video, Kathryn demonstrates more of the functions that are available through the math module, including factorials, square roots, and greatest common denominator. She also shows you how to convert degrees to radians and vice versa.
- [Voiceover] Let's dive deeper into the math module.…First we have to import math because we have…to have our module we're working with,…and we are going to start off by looking…at the factorial function.…To use it, you just do math.factorial,…and it'll get the factorial of any number you want.…And so to start off, we'll go 3,…and then we'll go ahead…and print this whole thing out.…And so this will just give us the factorial of 3,…and that would be 3 x 2 x 1 which will…give us 6 in the output.…
Another function that's just built into the math module…ready for us to` use is square root.…We'll go print math.the square root and so sqrt,…and then any number you want to get the square root of.…Here we'll just do 64 and the square root of 64 is 8,…and that's what we get in the output.…Another thing Python can do is help us find the greatest…common denominator between two numbers.…The name of the method we use is GCD,…and GCD stands for "greatest common denominator".…
And this method is really useful for reducing fractions.…
