Very very very tricky paper! Yesterday, I actually did all of the past papers that AQA had released, and that easily outstripped most of them
The answers I can remember that I got...
tan question was +/- root3 and -1
I think the sector/kite/shaded area question was 222units^2?
I got 1/root10 for the scale factor
because stretching in x direction means x/scale factor x/1/root10 = root10x as you have to square that, (root10x)^2 = 10x^2 I'm reasonably happy about that
the gradient I got log10 (1000/729)
if anyone has any other questions I'll endeavor to answer them
Two things to take away:
1) If AQA are setting all of their exams to this standard, I have got a ****e week ahead of me
2) Hopefully, since everyone I've talked to has said it was a tricky paper, we'll get generous grade boundaries
