I was disappointed at there being no trapezoidal or Simpsons Rule questions... They are the easiest 3 marks ever.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!!!!!!
Two questions that I know existed but I can't remember what I put down... :S
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 alrightwhat 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?

HAHA man u gotta be pretty pissed aye?, i bet ya it was a stupid mistake
woah marks back already, that's quick.
:|
What an awesome mark!
you're kidding.yeah that's it
and then you get t=35, and add that onto 8:55 and voila
I ended up subbing in 8:55 as a time after 12:00 as minutes and then i came out with 35
... I think.Thanks
aww danny. You are performing much better in maths than I did last year. I really hope you do get some state rank in 2 unit maths this year, make our school proud!
