hohoho.. I drew this by inspection... using coloured pens it's called "arts" and should fall under "Appreciating the Beauty and Elegance (extracurricular topics)" in beauty.GIF blue is the graph of sqrt(sinxcos^3x) red is its derivative green is the graph of sqrt(sinxcos3x) purple...

I can safely say that I spent most time on maths. But I dont do SDD :p I spend so little time on business studies LOL yet I came first in the year... But, hey, the best soln to this problem is to move to america :P

it should depend on the uni course as well. like arts obviously dont need maths.... and maths is bad for arts

it's c ;) (needed to download the syllabus to work out what financial expectation is haha... i dont do general.. and needed to work backwards as well) if you get first prize, you gain $99 ($100 prize - $1 to pay the ticket) if you get second prize, you get $49 if you don't get the prize...

Thanks Archman!! ^_^ I can't see how other people may want more time to work on it though. And if they want they can just not read the solution. Thanks again.

Hereby I request thee to reveal the proof to me. I am Roberd Frost. Two roads diverged in a yellow wood. O' which one should I take?? I took the one less travelled by. And I felt nothing different.

how do u know its not completely true? did u try drawing it?

umm.. the syllabus doesnt mention it but maybe they left it out.. coz its just an illustration of how hard the questions should be But I tried making random lines.. doesnt check if A B E D concyclic.. using Ms Paint.. and the points of intersections come pretty close and my ABED doesnt...

ill try my best to do it ;) but Xayma. r u sure u r not doing ext2?? coz.. its just strange looking at how much u write in the ext2 forum EDIT: doesnt look like I can do it :(

For one to manage such perfect amount of logic and decent amount of bullshitting, ext2 maths should scale highest.

Hi... looks like I have a question to ask :D It's from the syllabus, page 83. BF, FE, AE and BD are 4 straight lines as in the attachment. AE meets BD at H. Circles are drawn through the vertices of the four triangles ABH, HDE, FBD and FAE. Prove that the four circles have a common point...

but I was the one who told u in what post his sig was =p

what textbook do u use? im interested to buy one lol

hmm.. I dont think its the formula to find the volume of a dam ^_^ doesn't have any + and - sign indicating that it's not likely to be a formula applicable to real world applications. it also has repeated variables which can be simplified.. eg a^2o^2sjdi instead of aosjdoia well...

looking at table A1 from UAC reports, the max UAI might be 99.45. It seems to me that 88.8 is the UAI contribution which the best candidate in that year (2003 if you select it) got, based on his/her HSC mark which was not 100. need to ask Lazarus though oh, I'm doing 4U and my target UAI is...

there was also one of them in NEAP trial, either 2002 or 2003 im too lazy to find out

you wont need the cubic formula in any HSC mathematics courses.. inc ext2 (hmm.. maybe u might be asked to derive it with some guidelines haha) its just a formula that ngai came across this Q is from HSC 1994 so if u have the soln (MANSW or sumthing) can u tell us? Thanks. EDIT: no it's...

you still need some 2U formulas in 4U so u should be remembering all formulas ^^

Think of making acronym some words are often omitted :p

Ok (that tone sounds familiar... ;)) my apologies EDIT: no, this is not a real apology.. coz I dont think I committed any sin against Slide Rule
