    I'm in year 13, i'm supposed to be an A* student but i think i lack a bit of self-confidence sometimes and i hate being wrong lol :/
    Ahah, I know what you mean I really want an A* this year... Better get practising, I still haven't practised my S1 properly though need to start that... And I missed C2 in January so I have 4 maths exams this year... And I have all my other GCSEs :mad:

    Any revision tips for clashes?

    Same, I bascially need an A* and I'm determined to get it too :yep:

    oh S1 is reaaaallly easy when you just practise it. last year i was involved in an accident and i was out of school for over a month and i missed tonnes of maths (inc S1) but i just sat down one day and read the book and made myself understand every sentence and i got 95 ums in the end

    without trying to sound big-headed, maths is actually quite easy once you practice and do all the past papers. i find that's when my confidence goes up a lot more and well you're doing it in your gcse year so you would know.

    what do you mean clashes? 2 exams in one day? btw gotta run to school but i'll pm you later

    We shall get it together!

    Aah :console: well done though!!! I'm self teaching as well so hopefully, I'll be able to match that

    Yeah, I agree, it's quite monotonous as well after a while... Same thing in each paper, but then they change things in your actual exam! Like my mechanics!

    2 exams at the same time okay, see ya later

    i did [(x-1)/(2-x)]^2 => 2[(x-1)/(2-x)] x [(2-x + x-1)/(2-x)^2] => 2(x-1)/(2-x) x 1/(2-x)^2 => 2(x-1)/(2-x)^3

    gotta run to school!!!!!!!!!!!! :eek:

    Why product rule?




    So it would be 6[sin(e^x)]^2 mutliplied by the differential of what's inside the brackets which is e^xcos(e^x)? Is my differential inside the bracket correct?
    Correct!
