Applications of trigonometry
General Maths Units 1 and 2 (2023+)
This is another in the Applications of Triginometry series of videos for the Year 11 General Maths (VCE Units 1 and 2) course. Building on the last video which looked at the Sine Rule, I now look at how you can find missing sides and angles for other non right-angled triangles. With the Sine Rule you needed one side and an opposite angle. With the Cosine Rule you are given two sides and an included angle. There are lots of worked examples all used to explain the theory in a really easy to understand way.
