I think it should be (pi)(h^2)/2 but i may be wrong, heres hoping we get some marks regardless.

Yeh i agree, because you are integrating pi y dy, because x^2=y already. so it should be (pi)(h^2)/2

I found it ok easier than expected but hated q 9 and found it weirder than normal since most of marks were 1 wth? If I get 108/120 and considering I come from malek Fahd Islamic school would I get 90 + ?
ahaha I know right. Especially since qs 1 a) was worth 2 marks and can be done in 2 seconds, and then you end up spending like 10 min on 3 qs worth 1 mark each :S

I missed 10 b) iv) and v) because it was hard. TBH, I guessed part 3 but apparently it's right. r= P/4 ?


for 9 c) graphic, I think I'll lose 1 mark because I made the graph go above the x axis at the end....

9 b) ii) I failed. I don't know if I did i) right.


8 c) ii 2) was wtf.......... ??? did anyone get $1451 or something
yehh we had the samee answers 1451.84 or something and 9) c is right aswell

I think I got around 76% as a raw mark, does anyone know what this will scale to?

I think Kim needs to get more variety in shirts :/ Does anyone know how you solve Q5 (iii) ?

I think I got approx. 116/120 with the only errors made in that question above and 9d(ii)

omg, just realised that the 1 marker for y=2cosx graph asked for the COORDINATES of the point at the y axis. I only wrote '2', not (0,2)... do you still think i can get that 1 mark?

I think you do 0.5*S12 = 55283cents --> $552.83

Atleast that's what I got.
Oh I meant 5.b.(iii) sorry. I thought I had implied the probability one from my stupid remark about her shirts xD But it's okay, I've found the answer, thank you :)
