I dont think it was a piss easy exam... since only 4 ppl got 90 or more out of like about 80... everyone in my class is expected to get band6 in it (the 4u class) n the average was about 77? for our class..Pace_T said:hey haboozin, how did u do the iii in q5 of the exam?
its the one with the max or min volume of the sector r@= L n stuff.
i noticed the circle around it, so im guessing you had difficultly with it too?
i found one max or min value but it was a min value...
other than that, that was a piss easy exam man, i wish i had an exam like that. my teacher always puts in a super hard probability q right at the end. he can never do them himself the bastard lol.
we dont have probability because we havnt done that chapter....
I got 1 mark out of 3 for the last part that ur talking about.... i just never finished it for some reason..
This is what iwrote
differentiated it...
0 = 72(2-@)/(@+2)^2
then i just said therefore @ = 2
but the thing is @ cant be 2 because its not between 0 and Pi/2 (i think)
so the answer is that this is not the maximum....
