Sir, I have reached the end of your gcse further maths playlist and I just wanted to say thank you, you have saved my gcse further maths and made it more enjoyable because, thanks to you, I can actually do most of the topics. Thank you very much and you definitely deserve more recognition. I am not worrying so much for the exam tomorrow!

Thank you so much for these questions. Before I struggled with these since we skipped over the whole of geometry in lessons, but these practice questions have really helped me out.

Hey, I just want to say that I found out this morning that I passed my maths resit and I also have you to thank for it. I revised your papers every day leading up to it. Maths has always been a roadblock for me. And thanks to your videos it has finally clicked. Thank you 🙌

[@1stClassMaths]

Hello, on question 4, how did you work out that sinx/cosx = 2/5? I understood the rest but I was not sure about that. 🤔🤔🤔

[@1stClassMaths]

Rearranged the equation. Divide by 5 on both sides and divide cos on both sides

Hi sir, you know in Q9(b) for example where you factorise 5sin^2 + 4sin - 1
to become
(5sin -1)(sin +1)
is there a method to do it so quickly?
I've been trying to do the method that involves splitting up the coefficient of x (or in this case sin) and factorising the separate sides but I feel as though that takes too long.
Thanks sir!

[@1stClassMaths]

That would be what I would recommend I am afraid. Factorise x^2 + 4x - 1 first then just replace the x back to sin.

[@HariPopat]

@@1stClassMaths Thanks sir, after practising it some more I can do it faster now.
Further maths paper 1 was tough, but hopefully the grade boundaries will be low enough for me to get a nine.
Looking forward to your further maths paper 2 predicted video!
Thanks a lot sir
