Just thought i'd follow the trend.

For part (b) finding the shaded area, i found the area of the that triangle and then minused the area between the parabola and the line that was found in part (iv)

Anyone else do this?

i did..hopefully i got it right tho..

i think i got the area for iv) (ie, the unshaded bit of the triangle) to be 18
then i got the whole triangle to be 45
so the shaded area was 27

is that right..??

thats the general consensus at the moment, yes.

dammit i got the unshaded bit to be 12
