    Im starting to do weekly alevel papers in preparation and these videos are amazing. When you're at home and don't feel that driving pressure, being able to jump forward a moment to see the first steps to difficult questions really helps. Thanks, you're a lifesaver!

    Hi Mr Astbury, thank you so much for all of the help. I watch your videos every single day now for revision and it's been a tremendous help. Could you possibly also make a video going through 2019 Paper 1 as you don't have one yet - I always have to watch other RUclipsrs who aren't as good at explaining as you... THANK YOU!

    For some reason, I found some of these questions easy to understand than most of the Geometry questions I struggle on iGCSE Maths 😹

    I discovered your channel today & your detailed explanation has really helped me with this paper. I have just seen your A level playlist & knowing I have thoroughly explained videos to fall back onto gives me the motivation to do papers. Thank you so much 😊

    (Question 14c) Why can't you sub in y = k - x into 6 - (x - 3)^2 and then find the values of k for which the discriminant is greater than 0 (2 distinct points of intersection)?

      @SushruthRavishankar 8 месяцев назад +1

      Yeah , thats what i was wondering too?

    • @Hippogan
      @Hippogan 6 месяцев назад

      that is what you do for the 37/4 value but you only get 37/4 doing that and you don't get the other part of the range

    • @BBK583
      @BBK583 5 месяцев назад

      ​@@Hippogan the equation you get when working out discriminant , you can sub x = 5 as x=5 will be on the lowest (2 intersections points line) into x² - 7x + (k + 3) = 0
      and that gets you 25 - 35 + k + 3 = 0 which solve for k =7

    • @BBK583
      @BBK583 5 месяцев назад

      Because it will give you k is less than 37/4 because this does not take into account the limited domain of the function we have. this is taking into account the WHOLE graph. i.e. it doesnt stop at (5,2) so just think the 2 intersections could be anywhere after that as well

    At 1:23:50 really minor but you put in the x and y values wrong way round Sir

    Hey . So do they make it more clear whether to use in radians or degrees ? Im confused how you were meant to figure out you were supposed to use radians (question 10)
    Thanks

    • @Beesechurgersports
      @Beesechurgersports 5 месяцев назад +2

      You can only do calculus with trig in radians btw - and they use integration in question 10

    im confused at the end why do you make the green line go through the turning point

    • @BBK583
      @BBK583 5 месяцев назад

      it doesnt have to, he has just drawn 2 lines with a gradient of -1. and tbh the line is not to scale as (3,6) to (5,2) doesnt have a gradient of -1. it has a gradient of -1/2 so it is not accurately but rather it helps to visualise :)
