    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!

    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 🙌

    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.

    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. 🤔🤔🤔

      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
      @1stClassMaths  6 หลายเดือนก่อน +1

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

      @@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
