Countdown to Exams - Day 45 - SohCahToa

Today we delve a little deeper into the topic of trigonometry, focusing on SohCahToa (mnemonic for the trig functions). You will use this when finding missing angles or side lengths in right angled triangles. The first step will be to accurately label the triangle with Opposite, Adjacent and Hypotenuse. We then have to decide which trig ratio to use to solve the problem. 

You could use the formula triangles to instruct you or you could substitute values into the function and rearrange to solve.

Matt will guide you through solving trigonometry problems in the video below.
