    thanks
    if you do that paper let me know if you figure out the first question

    x^2+y^2=9

    I got a circle, center (0,0) and all the intersections at 3 and -3s but the markscheme says its at 2 and I cannot understand why that is

    If that's all there is to it, then the m/S is wrong..

    ive got the same as you :/ cant see how it could be anything else so im guessing MS is wrong
    do you have a graphical calc you can check on? I need new batteries.

    but it doesnt show it cutting the X axis at 2 it shows it cutting the X axis past two but doesnt say a number where it does :P it just tells us to sketch it hence why its just drawn
    it has the 2 for part B :P probs to help us/indicate where where need to find the volume for

    Almost finished C3 2010 Papers! Woop woop! I can't wait to get onto C4 Papers, really enjoying Maths.

    It's difficult but it becomes satisfying when you can do things you couldn't dream of doing before. Your understanding of how to Algebra works just improves tremendously.

    I am 100% Taking Maths Units/Modules at University! Grown to really love the subject.

    They should definitely teach A-Level Maths Algebra in Year 8/9 - it would make Chemistry and Physics so much easier.

    In other countries, as some friends were doing AS stuff at 14-15 :/ like remainder theorem, integration and differentiation :/

    x = 3\tan (2y-1)

    \dfrac{dx}{dy} = 6\sec^2 (2y-1) = 6 \{ \tan^2 (2y+1) +1 \}

    Sub in the original equation x = 3\tan (2y-1) \ \Rightarrow \ \dfrac{x}{3} = \tan (2y+1)

    \dfrac{dx}{dy} = 6 \left\{ \left( \dfrac{x}{3} \right)^2 +1 \right\} = \dfrac{2 x^2}{3} + 6 = \dfrac{2 x^2+18}{3} = \dfrac{2 (x^2+9)}{3}

    \dfrac{dy}{dx} = \dfrac{1}{\frac{dx}{dy}} = \dfrac{3}{2 (x^2+9)}
    thanks so much. asked my teacher and she even couldnt do it lol

    Many schools start the GCSE in year 9 now so pupils will be exposed to some solid algebra if they sit higher.

    yeh on the X axis co ordinate but for the one on the Y axis is says 2 for some reason. I guess it is wrong

    Do you ever have anything nice to say, four eyes?

    I'm a proud weirdo anyway... go revise, M2 tomorrow?
    You're beautiful
    lol weirdo
    Yeah i have to tomorrow but tbh i'm ready lol, i'v done all the papers and i know my stuff so just going to relax this evening and get my A Tomorrow and then mad eco revision after until tuesday and then get my A* in c3 and my A* in S3.
    Then get my A* in C4, flop STEP II, get A* in FP2, get A* in FP3 and get a 1 in STEP I! lool

    I don't think this is possible, unless you're doing a Pure Maths A-Level. You'll get a pure maths AS if you do that, at least.

    (Original post by reubenkinara)
    Even Pure Maths AS is C1,C2,Fp1
    Edit: It seems it depends on the Exam Board.

    Yeah, I should end up with pure maths AS at the end of this, which is C1, C2 and C3 on edexcel. I'm planning to go on to do the full A level, which will be just a regular maths A level since next year we're doing C4, S1 and S2.

    It's a little weird, I know, but it's because I'm in the maths group with the people who are doing further maths (because I got an A* at GCSE and chose the same block as them). For this group they decided that we'd do pure maths AS to help the further maths people with FP1.

    The rest of the year did C1, C2 and D1 - I'm kind of glad that I'm not doing that last one. It looks really weird. xD
