Question to whoever can answer:
On the integration question where it asked to find area of shaded region, I integrated the equation for line PQ, but instead of using the x-values for P and Q as my limits, i realised too late that I used the x-values for P and R. Had i used the right values my answer would've been correct, but unfortunately it was not. Do you think i would get any methods marks or have i lost all three there?
I'm just seriously kicking myself for making such a silly error that has probably cost me 3 marks.
