    I think it was dy/dø + 2x = sinx
    That paper was so hard, fp2 is normally so easy...
    It was with 2y instead of 2x

    My area came out 47.0001 or something like that. Which kinda makes up for that nasty angle that they put in.

    That had three questions on that we're not in any of the past papers I done in the past couple of days. They were the ones that had come up only once pretty much and I couldn't do them when I done them a while ago

    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 would be fine I think as long as you got the answer correct, but I am not sure if it is acceptable to put acos3/4 into polar coordinate.
