thats pretty harsh...especially when he helped you you can have a so-called 'life' and still enjoy maths... i dont get the "have you done this question before" as its pretty basic / standard so its not like it would take someone like affinity much time anyway

> 95 in all but english :(

heinz can you post ur test or something :P...just want to see the relative difference of difficulty as my test wasnt very hard :( ie 95%+

hmm yes...too easy for a qn7 imo

nah CM is competing with us :P ....jk

imo get a solid foundation of intergration and then dont practice direct intergration do volumes / mechanics or whatever with intergrations in it...kill 2 birds with one stone hehe

ahh whats a decent mark for a raw hsc 4u? keypad what did you estimate ur raw mark to be? i just did last yrs 4unit paper eheh

haha thats not a hint its basically solving it

if you do 4u next year i would. cause you would be getting the books anyway haha or you could just hope to get a 1991 / 1996 qn 7, which imo should be 4-5

haha ryan going on this site is studying some of the qns are harder than ones out of most the textbooks posted here

well yeah ryan i basically only had mechanics to learn this holidays :) -calculon i dont have past papers with answers, only the real past hsc's with answers and there are only ~18 so if i do them now, i wont have them to do closer to the hsc

mainly for ppl that have done the hsc.. is it better to do past hsc papers(answers), trial papers(no answers) or text qns considering i have now finished the course. im thinking i would do the dr.buchan trials and give to my teacher to mark...but i doubt she would get time to mark them...

:( you shouldnt hate those people you should respect them..i wish i could go into english exams with little preperation and still get in the top 5, like one or two people i know :(

"Prove that (p^2 + q^2)x^2 - 2(p + q)x + 2 = 0 has no roots unless p = q" i dont have paper here atm but i can almost certainly say you will need to find the discriminant and find when it will >= 0 and at discriminant = 0 p = q...just a thought

"Show that any degree three polynomial whose roots are in both arithmetic and geometric progression has a triple root at some value other than 0." the polynomial has roots x,x,x ie a triple root as it is the only possible way to be in a GP (increasing by x1) and an AP (increasing/decreasing...

yes...i can see it after i have the answer..

i dont use a tutor personally but i hear that prior is good for maths

perhaps..the limiting sum of this series is a root of multiplicity x of a polynomial p(x), show this is true, hence factorise p(x) although i doubt something like this could be asked..or perhaps they could give polynomial of degree infinite, written as a sum using sigma err.. i giveup

haha i cant explain..but its ..just has to :( My answer shows the ratio dependent on a, but not p or q - is this consistent with what you are thinking? yes this is what im saying, and im saying its true because the line PQ is similar for both the triangle and the area of parabola.. draw...

think outside the square ryan....haha the possibilities everything would be like a dot or a line
