A Year 10 recap for Trigonometric Ratios which have already been covered in year 9. In this video, we look at what a ratio is and how we can leave answers in terms of a fraction.
This video shows how to apply trigonometry to problems in 2 dimensions.
This video looks at bearings in Mathematics. What they are, where they come from, home they are used in real life. There are examples and lots of discussion about where they can trick you.
This video shows you how to find the area of a triangle when there isn't an obvious height and base length connected using a right angle. It builds on the work done previously on Sine Rule and Cosine Rule but showing how you can find the area of a triangle if you know the size of two sized connected by an included angle. Lots of worked examples are done and fully explained in an easy to understand way.
