About this lesson
This video is part of the Further Maths Units 3 and 4 course and the Measurement and Geometry module. Having taken some time to teach ways to find missing sides and angles using the sine rule, cosine rule and trigonometry, I now look at how these can be applied to some real world situations. I look at what the angles of elevation and depression are. I explain bearings and then move onto triangulation. There are a number of worked examples (some quite hard!) which frame the theory. I do all I can to explain the theory in an easy to understand way.
