    I thought it was difficult, but not overly so.
    I attempted every question, unlike my C2 retake.
    I wouldn't be surprised if it was my highest mark! I think the maximum marks I would've lost is fifteen.
    But then again, I thought I got 90+ in Stats, and that didn't work out so well for me.

    I thought it was pretty standard? :/ The only 'odd' question was the differentiating x=tany one, all the others questions were no easier or harder than previous years (in my opinion)
    That question was pretty good imo.

    Just find dx/dy then find the inverse (i.e. dy/dx)

    I considered using implicit differentiation but I don't think I'd have got marks for using techniques not officially covered until later in the year.

    Why don't all of you people rep Arsey, he does solutions and clarifies questions and gives grade boundary advice. Not even my own tutor does that (not without hassle from everyone else), AND I PAY HIM u___u

    8 - yes you will need the other two (one of the reasons it is very hard)
    9 - you are told x>1 so fg>3 not >=
    great...

    oh well

    i lost 8 marks minimum ... dunno what else i have make silly mistakes on

    For question 4. (i)

    y= ln(x^2+1)/x i used the quotient rule then found hard to simplify so i crossed it out, i then changed y to ln(x^2+1)x^-1 and differentiated.

    i used vu' + uv'. Is this wrong and if so do they mark crossed out solutions?


    Also if i got two values for (a,b) in 7(c) and one value and method is right just i used a value out of range do i still get all the marks or less because i put down a wrong soluion as well. Thanks for any replies.

    I jumped a step and immediately said the inverse was cos^2y which threw me off for a bit since I was confused what to do from cos^2(arctanx). But once I went back to sec^2x I got it.

    for a and b, you only lose final mark for the answer

    I felt the paper went well. Struggled on two questions, the 3^x * e^(7x + 2) = 15 and differential of ln(x^2 + 1)/x. Nice to see the explanations, annoyed I forgot to separate out e^(7x + 2) into e^7x * e^2! Hope everyone got on alright.

    made stupid mistakes. like the x=tany question. i was puttin in back into part 1. lol. evn the 1st question was kinda hard.
    I did that! I feel really silly now looking back at it. It could of cost me an A grade
