at least its one of the more difficault volume questions.

yea but its not just based as ur HSC Mark. well someone last yr did get 120/120 (since u only get 100/100 if u actually get full marks) but the person who came second could ahve got 120/120 aswell... just a lower assessment mark. the person who came second could've got 118/120 and a higher...

no acceptance no rejection... they forgot about me :'(

oh cool, easy as ... never seen a question like this...

could it be 24?? or 11 but dividing by that could give you a remainder in the form of ax + b , but then again a could be 0?

no, well some of the 1990's papers are so hard. They give you no lead to the question. Harder than CSSA, Grammar, HSC or any other 4unit paper. This is 4unit paper btw, if your talking about 2unit that doesn't really count if its not really hard. Most of the students would be doing 4unit...

get the maths assosiation book with the past 10 hsc and solutions. (its really good and explores most of the common methods possible of gaining a solution) there should be quiet a few past school papers around but not many with solutions... theres quiet a few here...

theres books when marks were revealed in the old hsc that tell us the highest lowest average etc etc.. (lowest is pretty boring ... 1... 2. ... 2. ... 2... 1 something stupid like that) the lowest average was for 1993 and someone got 120 in that. should just look at that book and stop...

I = x^2/(x^2 + 4) + 1/(x^2 + 4) I = 1 - 4/(x^2 + 4) + 1/(x^2 + 4) = x - 2tan^-1 x/2 + 1/2tan^1 x/2 = x - 3/2tan^1 x/2 + C

yea but i dont have the last page (Q8) so its a bit sillly cause i think the other questions r pretty easy (or CSSA standard)

i donno i dont think it was that hard... i got 103.5 this yr... but the guy who got 97 was REALLY good. he just didnt know english so well.. he was first in shanghai china before he came to australia as an international student. his name was random. haha

turramurra high...2004 my sister got 73/120 in that and hsc mark of 93. only 3.63% get under 50/100.... so they probably get at least less than 20/120.

they're missing 1 very famous maths teacher.... donno if thats the reason why it wasnt so difficault? i wanna try 2003 and compare

i hope this yrs HSC is very hard.. it filters out people and widens the gap of the able and not so able invididuals. It is more fair in a way.

ur looking at 12/120 ? sisters friend got 15% (18/120) in the trials and got 62 HSC mark. another person in the same trial got 97/120 and got 98 in HSC 2004

Eng Adv: 72% --- 17/44 Math ext1: 87% -- 7/42 (ruined it :() Math ext2: 95% -- 1/14 (scaled from 86%) phys: 80% -- 3/35 SDD: 90% -- 1/10 IPT (2004): 86% -- 2/18

can anyone do this non graphically: x >= 3sin@/(2 + cos@)

i think CSSA is the harder one... i did the 1999 James Ruse one and that was so hard compared to SGS or CSSA 2005. They give you like no clues. 0 lead :'(. you can try it if u like: http://www.boredofstudies.org/mirror/4u/jamesruse1999.pdf

i know why i couldnt do it now because of the a + b + c >=3 cubedroot(abc) but is cauchy in the syllabus?

i dont get the first 1?
