YESHHH xD lol girras been rising up like ten ranks every year .... hu noes ... by the time we are in year 12 we might take down ruse :D

OOH ....i got it thanx....lol i avoid turning it into a fraction at the bottom...i dunno y.... it makes it look more confusing ...i guess ill get used to it though xD

oh ok....i get it now....so its just like finding horizontal asymptotes and in the end ur left with y=x so that's the oblique asymptote? thanx guys

so u just observe and infer? isnt their like any way apart from that? like wen finding the horizontal asymptote u use lim x->infinite

can someone solve : (sin^2 (x)- cos^2 (x)).(1-sinxcosx)/cosx(secx-cosecx)(sin^3(x)+cos^3(x))=sinx i expanded the difference of the two squares and also (sin^3(x)+cos^3(x)) and then crossed out and was left over with sinx-cosx/cosx(secx-cosecx).....leading me to sinx-cosx/1-cotx ... now what?

im planning to use those 192 page tudor grid books for maths...im not sure if its sufficient though and as for other subjects i got 196 page exercise/binder books

hey guys umm..i noe how to find vertical and horizontal asymptotes but how do u find oblique asymptotes? e.g....oblique asymptote for y=x - (1/x) is y=x (got this example from cambridge) thanx in advance ... soz for my noobness :cold:

just check my sig' for my subjects for prelim i mite take ext 2 maths for yr 12 and drop down to advanced english...depends how i go in prelims :read:

i feel sorry for u.....conquering chemistry is a really good text book for chem...is it possible to buy it online? are there any dymocks stores around ur area? if there is im pretty sure they sell conquering chemistry text books.

lol APCSfan...how the hell did u end up on this thread? rofl more cushion for the pushin' ? lol

wat do u actually do in preliminary/HSC english? do u do comprehension or is it mainly riting stuff? and wat do u write about?

are u getting these questions from preliiminary cambridge textbook? these questions look very familiar.... lol xD

Re: Help with textbook for preliminary? im taking extension english as well.....and i dunno how to study for it ? or wat text books to use ? some of my frendz use the excel preliminary english book...is that good?

Re: Help with textbook for preliminary? i use cambridge 3U year 11..... i have a maths tutor to help me understand the stuff properly...it has decent exercise as well :) but cambridge has no worked solutions....which is gets really annoying sometimes :(

im having the same problem....i mite change from biology to economics ... but im not sure..... do u need to put in more effort into biology or economics to get a good result?

haha i used to go to alexandria park COMMUNITY school .... but now im gonna go to girraween high for 2009 xD :devil:

oh yea....my bad... kk i can work out the rest thanx....i need to memorise the trig identities properly x(

after reading through the 'conquering chemistry' book and the Jacaranda Preliminary Physics book i reckon chemistry looks more interesting xD CHEM>PHYSICS>BIO

iv had a mental blank today....and im stuck with this question : sec^2 (x) - 2tanx - 4 = 0 solve for 0'_< x_<360' its prolly really basic but as i said iv got a mental blank :( thanx in advance
