i) 1/2 * 31/63 * 15/31 460/3906 230/1953 ii) 460/1953 iii)1493/1953 i have no 2 unit questions.

The first line! \int \frac{1-x}{1-\sqrt{x}}dx=\int \frac{(1-\sqrt{x})(1+\sqrt{x})}{1-\sqrt{x}}dx =integral(1+sqroot(x))dx =x+(2/3)(x^(3/2))+C It's not that hard, im not sure of the extent of the 2unit syllabus

Methinks perfect square in the numerator is an easier method. Actually, your first step is wrong! btw, that was a trial ext2 Q7 (c) worth 2 marks. dont ask 4 the method but: d[tan^-1(x^4)]/dx =[4x^3]/[1+x^8] i reiterate: integrate: [1-sqroot(x)]/[1-x] GL ;)

the world works like this: do maths or have a social life. just answer the damn question!

10 terms of arithmetic: S10=10/2(2(-6)+9(-2)) =5(-12-18) =-150 10 terms of GP: S10=[2(4^10-1)]/[1-4] =2*1048575/3 =699050 .'. 699050-150=698900 now, class! integrate: [1-sqroot(x)]/[1-x]

sec(C)? ahahaha i c what u did there! integrate: [1-sqroot(x)]/[1-x]

Are u sure? y=3x^2-2 inverse: x=3y^2-2 x+2=3y^2 3y=squareroot(x+2) y=squareroot(x+2)/3 ?????? OH FUCK! derivative not inverse!!!!

Are u sure? y=3x^2-2 inverse: x=3y^2-2

I know teh phone thing, but i was mking sure bout the camera

LOLZ!! if this was a tyre analogy, i think i popped my brain by pumping it up too much.

Are we allowed to photograph our paper after we're done?. If i could, i wouldn't use my phone, i'd use a normal camera.

Does HSBC have subsidiaries in 77 countries or is it more? I have the 2006 book and i need info by next tuesday!!!!

My maths teacher said they'll give you the separate BANDS for each subject as well as you ATAR using 2 different organisations (cbf knowing their names)

2 ppl answer and no next question???

WOOT! entire week before physics, than another entire week before engineering. BUT 2 exams on the first day!!!:angry:

BAHAHA! Staggering in the amount of recent losses!

XD I remember my laughter one. It was a gory description of soldiers in Iraq, and at the end, the officer is just thinking "what for?" and my last line was 'without us, there could be no laugter.' This year, since everyone says don't do violence, so i stepped it down a notch and did adrenalin...

Booganee, pardon my french but that was ABLSOLUTE SHIT! Do't your techers write in red NO RETELLING! Lyndallg, I thouroughly enjoyed your simpe to undersatn analasys. You're a living legend! Thanks for this on the day before my trial, now I've got a boner.

if they were from another religion they'd be dead and therefore unmarriable. unless you can marry corpses/zombies? if the religion had managed to take over the world, as they attempt to, there would be no problem.
