Description
Just when you thought it was safe to get back into the water, back comes Pythagoras' Theorem. This video forms part of the pre-learning which is going to be needed for the rest of the chapter in this Further Maths course. It takes some time to recap the theorem including where it comes from and how it is used to find the missing sides of a right angled triangle. After some awesome theory, great examples show how it can be used. The CAS calculator is also used to show how we can solve these problems with ease.
