    You'll lose 0/1 on what was a difficult question so I wouldn't worry.

    isnt it e^(ln(1/144)+2)=y

    2=2lne=lne^2 so ln(1/144)+2=ln(e^2/144)

    Last year was way easier
    With due respect, I am saying this without all the added exam stress.

    Have a look at what people said last year about their c4 exam, every year people always say "This is the hardest exam ever".

    It's not! Have a look at June 14 c4, the questions there were much more challenging then what we had today.

    I did the same, I just assumed i flopped the whole Q but does that simplify to the right answer?
    I'm pretty sure it does I haven't tried though because I'm not feeling doing more a level maths after I'm done ahah. Without the simplifying bit the differential equation was decent and getting it in the right form was the really tough bit so I think i might have got it right? I'm just not sure how many marks there would be for simplifying it

    I was an idiot in the last question and left it as (9/1296)e^2

    Will I lose a mark?

    It was very stupid of me to put it like that but I do think it's in the right form.they asked for Ae^x. A=1 and e=(ln(e^2)/144)
    No A=e^ln(1/144)
    A= 1/144
    So is (1/144)e^2

    I think

    unlucky dude the last one is y=e^ln(1/144)+2
