Does anyone know if i can download these? The marking guidelines that are avaliable from Board of Studies are quite useless and just say things like "most candidates did/didnt do well in this question

I don't think they're available online, but you could post specific questions that you need solutions for.

see if you can get hold of the success one book for 3u.

worked solutions from 87-02

also the green book of past papers by mansw should also have worked solutions

Ok i also need answers for a specific question in 2001. The question is 8 c i. Im not going to post the questions cause u need the diagram etc... The SP package for 2001 maths is really fucked up i recon. All the band 6 answers are different to each other.

ok 8c) 2001 HSC answer is as follows:
i) dy/dx is max at the narrowest point so at ~2cms
dy/dx is min at the 'fattest' point so at ~7cms (think of it like ur pouring water in a narraw tube, its gunna fill up quicker than pouring water in a wide tube rite)
iii) it takes 5secs to fill the glass....therefore t=5, y=10
and we kno that concavity changes at y=2 and y=7 cuz we jus did it in part (i) so yeh jus gotta draw the graph now and it shuld look it does in the answers

i just did the 2001 maths paper... i can't get the same answer for Q10 B ii as the solutions!!!
i think they sub'd theta back into an equation that's wrong (or maybe i did ) but they had 8tan, when i think it shouldve been 8+tan.... can someone tell me if i did something wrong? =\

how do u draw the curve? like, how do you know whether it starts concave up or concave down?
