    anyone confident about what x tends towards as t tends to infinity? I guessed infinity, anyone know???
    this is question 4a or 4b I think.
    I got r/q or something, because as t tends to infinity e^pt/q tends to zero.

    Answered everything probably got all the methods correct made some wrong/incomplete calculations, what do you think I'm likely to get if all the working was correct?

    As t tends to infinity e^-t tends to 0
    So x = r/q

    I got it tending towards a fraction of the constants, p/q or something. Cant remember exactly and wouldnt say i was confident either lol

    I'm probably really stupid for doing this but I kept it as costheta= 3/4 and used arcos3/4 all the way through. Lord help me.
    That't what I did too! 😭

    **** Edexcel *******s!! FP2 is usually guaranteed 75, that was atrocious!
    The tell arsey he can't do mark schemes and now they violate is in FP2.
    Settle down

    WTF what question was that?? How many marks? I remember the integration but not this!

    Does anyone know if there's gonna be an unofficial mark scheme at all? Thanks

    Yes tell me. That question killed me!!
    I do it like this
    Let t = intergrate e^2x sin x
    then you by part you got
    -cosx.e^2x + intergrate(2e^2x. cosx)
    then by part again you got
    -cosx.e^2x + 2 ( e^2x. sinx - intergrate(2e^2x.sinx) )
    Therefore
    t = -cosx.e^2x + 2e^2x.sinx - 2t
    t = 1/3 ( 2e^2x. sint - cosx.e^2x)

    No complex transformations either.. Spent so long revising them too. Christ sake edexcel
    Yeah the stuff that I was getting wrong that came up a lot I practised so much and then it didn't come up

    Probably 65-70/75

    I await an unoff MS. But goodbye A* sigh. With the way it's been it'll be 72 A* which I'll miss even if I'm on the higher end of my range.

    Dire, that paper raped me.

    For showing the complex roots, do you just draw the arrows to the complex numbers or should you draw the circle? Will it even matter?

    I managed to get the summation to cancel since that was in a past paper, rushed the addition though so I may have wrong coefficients.

    I'd say maybe I lost 15 marks in total. ****ing hell.

    did you get c as 2/3 ?

    It'll probably be 67-68 for A*. I would say around 6-7 marks in that paper were out of the ordinary.

    No idea.

    Got something like 16 for the area on Q8, looks like I'm screwed.
    I by parted it twice and moved the integral over to the other side (the FP3 by parts trick) and same answer for area, but I think it's wrong cause the shaded area isn't that much smaller than the circle, which has area pi*(7/2)^2 or 38.5.

    How did you find the F2 IAL paper?
    Not typical questions like past papers, that's my thought. The calculations(integrations) are tedious... #sigh
