wooooooooooooooot!!!! it is going to be quite sad though. cant wait till summer, PARTY TIME!!!

yes u have to show both steps.

thats just provinf there mutually inverse e.g. f(x)=x^3 , therefore f^-1(x)=(3root)x f^-1[f(x)]=f^-1(x^3) =(3root)(x^3) =x f[f^-1(x)]=f((3root)x) =((3root)x^3 =x hope that helps

i think this is it: let u=sinx , therefore du=cosx.dx (int) u/(2-u^2)^-0.5 = (int) u(2-u^2)^-1.5 = 2u(2-u^2)^-0.5 + C =2u/(2-u^2)^0.5 + C = 2sinx/(2-sin(^2)x)^0.5 + C

it wouldn't hurt. sometimes you can make some silly errors in tree diagrams and you can use the more complex formulas to back up your answers....thats what i do :)

Re: Trial Timetables? my timetable is the CSSA timetable and its looking ok for me.

actually i've seen this come up a bit in past papers (particiularly from private schools) Given v = dx/dt d^2x/dt^2 = d/dt(dx/dt) = dv/dt = dv/dx.dx/dt = dv/dx.v = dv/dx.d/dv(1/2v^2) = d/dx(1/2v^2)

nice rhyme

1. 1 - (12/15 x 11/14 x 10/13) = 47/91 2. a) 13/52 x 12/51 = 1/17 b) 13/52 x 13/51 = 13/204 c) 13/52 x 39/51 = 13/68 im pretty sure that they are all right although someone can correct me if im wrong :)

+1....hate it so much

haha u do really need to get off this site just take one day at a time and im sure u will complete everything :)

what i've been told, is that it doesn't really matter what idea of your story is, it's the way you describe all the features in the story (if you know what i mean). and yes, you do have to write a short story in both the trials and the HSC.

thats exactly my problem, although i'm working on it. i think the only way to get better is doing a wide range of questionns i.e PRACTICE!

i have pretty much finished all my essays for trials. the only problem i have, is that im not sure if i should memoreise them or just know the main points? And also, should you memorise your thesis or make up a thesis in the exam room that suits the question? opinions please?

there is a surprising number of losers that care whether there are chicks or not in their course. p.s. sorry i just had to say it lol

my stress levels are like MORE than "OMFG!!! Totally stressing out... >_<" :spzz: nah im actually taking it easy atm but ill have to up the ante the next couple of days coz of trials and assessments

day 2 obviously lol

:headbang: nice mate

its pretty good although quite basic....i use it to refresh my mind every now and again on the topics i havn't done for a while
