    Correction - at 18:10 the final answer should be 53.4 not 53.5 🤦🏼‍♂️ no idea what I was looking at when writing that! - I’m only human!!

    Honestly I was a little afraid to look at this part of maths, but when I finally wanted to give it a chance and get it over a done with, I immediately thought of your channel because you make everything seem so easy and fun, and this video just proved my point. Please never stop.

    GREAT LECTURES! Many thanks. Question: When using the Sine Rule a/SinA = b/SinB = c/SinC, is it OK to use d/SinD in your calculations. For example, I've labeled the triangle points A, B, C, D, etc., where D is an angle and d is an opposite side I want to use. The labelling just matches up, without having to re-allocate letters. Thanks in advance :)
