Introduction

Defining sine, cosine and tangent

Applications of geometry and trigonometry

Year 12

This video is the start of a new topic which looks at Trigonometry. It's important to note when we use trigonometry (right angled triangles only) and how to label a right angled triangle's sides. The theory is explained (building on the knowledge gained in Year 9) and examples are shown for finding side lengths and angles. I also look at how there can be multiple angle solutions for triangles using sine and cosine.
