    How did it go you guys? Last year it was **** easy, so I'd imagine they made it pretty hard this time.

    Yeah I do.

    X = come back later unless you want 65 warning points.

    K = put this in your head and keep it there.

    Y = remember it for future, answers will be up later, wait patiently.

    Therefore applying the chain rule, d/dX x dK x d/Y = go have a kebab for now and come back later.



    Also, as an above posted said, you will know when it's time. It might be time right now, but come back later to be on the safe side. :dance:

    Some TSR user posted this solution a while ago.

    3^xe^{7x+2} = 15

    3^xe^{7x}e^2 = 15

    ln(3^xe^{7x}e^2) = ln(15)

    ln(3^x) + ln(e^{7x}) + ln(e^2) = ln(15)

    xln(3) + 7x + 2 = ln(15)

    x(ln(3) + 7) = ln(15) - 2

    x = \frac {ln(15) - 2}{ln(3) + 7}

    Ah. Well the good thing is that I got it to the bit before you need to factorise out the x :woo:

    The bad news is I ran out of time...

    muchos thankos

    i had been struggling with it for around fifteen minutes until i got to that stage, and then i noticed you could factorise the x and i was so happy that i was about to get five more marks

    Ditto.

    It took me about 10 minutes to remember you can treat ln3 as a real number :P

    yeah you could say that :emo:
    aw you guys shouldn't worry. Last January 2009 C3/S1/M1 were very hard and they lowered the grade boundaries a lot! And then Jun09 C3 paper was so easy it was unbelievable :p: though the grade boundaries were bit high, but still. So don't worry, this summer you will get a better paper
