look at what you have, then look at the formula sheet and 90% of the time you can tell which formula you need. or, you can use 3u like rama said. :/ because of 3u everytime i see max height i think make y' = 0

where are you getting these figures from?

69% is about 57/84 which seems a bit low for E4. but if so, then im stoked :D

either paper 2 or legal, mark-wise english, difficulty-wise maybe more legal

i had a fly annoy me during the maths extension exam :@ good thing it wasn't around fo rthe whole 2 hours tho

i tried 4U, too much work

SOOOOOO glad there were no binomial Proofs hahahaha, and the relative ease of the SHM question suited me quite well also :D

70/84 or there abouts

yeah, any binomial calculus will destroy me

Assume true for k 33k + 2k+2 = 5M 2k+2 = 5M - 33k ------------------ 1 Prove true for k+1 = 33k x 33 + 2k+2 x 2 = 33k x 27 + (5M - 33k) x 2 --------------------- from 1 = 5 x 2M + 33k x 27 - 33k x 2 = 5 [ 2M + 5 x 33k ] Edit: bah beaten by almost 10 minutes, oh well, mine...

THIS is real english, if i did that i might've actually enjoyed year 12...

quote me and find out. and i put the answer as 2018, but i wasn't erally sure.

yep i only saw it because i put in the ^ thing to see the parallel lines

you mean we DON'T have to derive it?? haha

q8a - pythagoras' theorem, substitution and maxima/minima q8b - integration of polynomials (?) q8c - superannuation q9a - calc of x, dx/dt, graphing sin/cos/tan graphs q9b - similar triangles, limiting sum q10a - co-ordinate geometry, algebra manipulation q10b - obscure...

HOW were the questions 3U standard?

apart from q10 a, which only LOOKED like a 3u question, which parts in particular was there controversy?

wow congratulations! have fun laughing at people who have their exams on the last day! (aka me)

oh THAT article, i thought it mentioned a specific poster. a teacher from my school made that article as well (hahs)

yeah i personally think q8 was more of a challenge than q9 (except i had almost forgotten how to prove similar trianges :D)
