Circular functions

Mathematical Methods: Units 1 and 2

Introduction

This is a topic which, without fail, appears on every known exam. Well ... so long as it deals with trigonometry! I take some time to look at why, when we have trigonometric equations there is more than one answer using various graphs.
Knowing there is more than one solution, I look at how we can use the two traingles, then the unit circle and some good old fashioned calculator use to find all the missing angles both with degrees and radians. I even look at how to decode the general solution when you dont limit the domain.
Complex examples are studied and full worked solutions explained. This is the most comprehensive video I know which explains how to find all the solutions to trigonometric equations.
I hope you enjoy watching it. Let me know if there is anything you don't understand.
