Hi, I absolutely love this channel! You're my SAVIOUR, so I have subscribed already. Would you mind doing a video on geometric sequences, preferably before the GCSE 2024 maths exam? I know there is a lot of hard work behind that but really need that. Would be highly appreciated!

12:09 this might be a dumb question but how would we use trigonometry to find out A and B and in what cases would it be a preferable method to just finding the equation of the tangent.

At 9.43 when we find k= 6 and it is -k=-6 why have we turned it to a negative k please 🙂

I’m confused why at 8:47 the points are (-5, k), but the labels are +5 and -k. Why have they been switched??
