About this lesson
This video looks at what a trigonometric ratio is and how we can find them. It's part of the Year 9 course relating to Pythagoras and Trigonometry. I also spend time explaining what SOHCAHTOA is and how we can use it to find missing side lengths and angles when we have sides and angles given to us. There are a lot of worked examples and I make sure that the theory is explained in an easy to understand way.
