what the hell! how did you guys get that? after putting f'(x) to 0 all i could get for t was zero. then i subbed heaps of diff numbers in and kept getting zero?




for that ugly 15/2 cubic curve question, did you guys get like.. 15? i added/multiplied some shit in the intergral by 4 i can't even remember.

NO TRAPEZOIDAL OR SIMPSONS RULE QUESTIONS!!!!!! :)
I was disappointed at there being no trapezoidal or Simpsons Rule questions... They are the easiest 3 marks ever.

i think i got 31.0

and for the maximum volume one, i think i got 1400/pi litres coz u didn't need to use calculus

Two questions that I know existed but I can't remember what I put down... :S

I'm pretty sure I got the pi^x question though... I have no idea what the answer was. -_-

:rofl2: oooer, new emote.

From memory, f'(x) was a sin curve, so t=0 was the first x intercept, you had to find the next one. Initially I could only find t=0, but worked it out alright

yeah that's it
and then you get t=35, and add that onto 8:55 and voila :)

Really easy exam i was surprised with the last question as it was really easy compared to previous years. Um with taht inetegral question where it said f(x) =15/2 i split it up and had 15/2+ (4x) with the upper and lower limits.

you're kidding.
i subbed every number up to 30 then gave up
fuck my life. i missed like 8 marks. GRRR
I ended up subbing in 8:55 as a time after 12:00 as minutes and then i came out with 35 o_O... I think.

I hope I'm really close! I think I threw away a lot of marks there.
