Your explanations are the best. No beating around the bush. Just straight to the point

I have watched a lot of videos and noticed you always start off video by saying ok.

Hello, If we were to be given this is the Edexcel A-level maths exam would it give the starting drawing or would you need to draw the rectangle with the triangle inside yourself. (Also I know the way I have written this sounds confusing but It's difficult to explain).

I just checked the edexcel spec and it just says about using these gormulae not deriving them - do we need to be able to prove them?

So if COSA and COSB were negative what would happen to the signs(of course it would change) but what would it look like.

Would we be expected to prove these formulae in an exam or are you just showing us the proof for completeness?

Hi, do you have a video where you solve equations using the compound angles formulae?

Hi sir, do we need to know the proof for AQA?

7:27, replacing each of the y with -y? It feels so wrong
