Introduction

Exact values of circular functions

Circular functions (Year 11)

Year 11

This video looks at how to find the exact values of common angles using the two triangles. This is one of the most awesome ways of doing maths. If you don't understand this by the end of the video then I've not done my job properly!
Once we have worked out how to use the two triangles to find the most common angles, I then take time, using examples, to show you how you can combine your understanding with the work done in previous videos on the Unit Circle.
This is the most fun you can have in Mathematics. I promise ... or your money back!
