what raw do you think you got? also for 4unit..

yea mate calm down, justchillin does love himself - but after all he does know what he is talking about... its actually in the syllabus for you to be able to know how things differentiate things to get its integral... and thats what he was doing - clearly... anyways, not only is that in...

3313 this year. http://www.boardofstudies.nsw.edu.au/bos_stats/hsc05_mediaguide.html

well thats what this year was all about... not really go in depth with any part of the course but just have questions which put people off.. (so the truely good people still do well - but the ppl that just cram and dont understand the course fail misterably) there's even 2unit tests that...

or Geoff Gaha? Where is he?

Q7b ii 0 < A(1/3^(3/2)) - A/3^(1/2) + 1 A(1/3^(1/2) - 1/3^(3/2) < 1 A((3 - 1)/3^3/2) < 1 A(2/3^(3/2)) < 1 A < 3^(3/2)/2 A < 3.3^(1/2) /2 theres actually 2 ways to do this to get u the answer!! either minimum value is bigger than or max is less than (i did the max is less than...

yea what wanton-wonton did was right.. you half it then half it again (to check your answer) and its def 0.7... it was actually in an old hsc where they did the same thing and people got tricked with the same thing.... this is what this yrs's maths was all about - help put off people...

and Q6b ii ... is it 44.82?? eek i think i wrote 40.82 3d ii differentiate x = l/2 check its a min (differentiate again or something) put it in the equation L^2/4 - L^2/2 +12 = 0 12 = L^2/4 L^2 = 48 L = 4 srt 3? ??

for Qbii, for it to have only one solution the minimum has to be bigger thna a root (ie put minimum in there and u have to get bigger than 0 that works out and it has to be true since if min is bigger than 0 then it'll only have 1 root and that is when the max is coming down...

just do the solutions to all of em - put it in one word file and give it to Timbk to put it on the first post i hate this searchign everywere to see how much i got

yea 78 for me too i think... im not very happy... havnt done well in both 4unit and 3unit

Well, What did you think?

well the bad arse schools in maths have been james ruse, syd grammar and syd boys. and james ruse has been doing really well in the recent years, also whenever people here james ruse they go *drools*, so that itself makes the story more appealing.

well, its easier to find the (potentially) best kid there than it is at a random school... they probably just go there and go... who was the maths dux at ur school, in case of your year people said Jason Chung - so they interviewed him.. and well Mok owns science.

Sometimes even the best mathematics students in the state have trouble adding up. "It wasn't hard. I just didn't time it right so I didn't answer it all," said David Yang, a student at James Ruse Agricultural High School, after emerging from the 4-unit mathematics exam yesterday. His...

Next Question: Using the substitution t = tan@ , or otherwise, show: (tan2@ - tan@) / (tan2@ + cot@) = tan2@ A 6 is scored in cricket game when the ball is hit over the boundary fence on the full. A ball is hit from 0 with velocity of 32 ms^-1 at an angle @ to the horizontal and...

depends how you solve it but if you simplify you will get Terry Lee's answer - which is the best - simplified answer.

but, he didn't... he got 99 i am 100% sure. I am pretty sure a few ppl got 99 I don't like this method. 42? super ew.... the whole state would have got E4. The exam was hard, but not THAT hard... there was a lot of questions which many people could have done to get at least 42...

Question 24. <b>Q25</b> The probability that n car accidents occur at a given set of traffic lights during a year is Pn = {e-2.6x2.6n}/n! By considering values of n for which Pn+ 1/Pn >= 1, determine the most likely number of accidents at this intersection in a given one year...
