lol i answered that above :D

arggg! 2002 is REALLY annoying me.

People who do tutoring are not necessarily the ones who succeed in 4unit. If you are capable, you don't need tutoring. Although obviously having someone help you out at home will help. and I agree that tests should have more difficult questions. It distinguishes between the students who...

yeah, great maths teachers are really patient. hehe, mrs arnold teaches us, she's pretty encouraging and always explains the thing a million times if we dont understand it :)

yay! I undertand! thanks Riviet! :)

Hey, for integration by parts I always get up to the same step but can't keep going. It's where you gotta sub the "I" thing back into the equation. for example, here's a question from the 2005 CSSA paper that I can't do. Q2) e)i) If In = integral between 1 and 0 of x(1-x)^n show...

you don't have to... all you need to do is say that it's a tangent where they meet and that means that there's a double root. :)

this one's pretty simple once you get the little trick: Let roots be a,b,c you know that roots a + b + c = 0 therefore a + b = - c b + c = - a and c + a = -b now we can substitute into the expressions that they've given us. (a + b) / c^2 = -c/c^2 = -1/c and so on. now...

yup... i do i do... i've done up to half of question 5 lol

ah okiez, thanks.. :D

after drawing the parallelogram label the angle that is made in the bottom right corner. the angle would be 2pi/3 since the side OC bisects BOA, which is pi/3 (parallelogram rule) after you've got the bottom right angle, you can use the cosine rule. OC^2 = 4^2 + 2^2 - 2*4*2cos(2pi/r)...

je n'etudie pas francais :D mais j'ai lu des livres au liban... j'ai lu un-demi de harry potter en francais.. ca etes tres dificile :D and haha sorry if the above has a million grammar and spelling mistakes.. haven't done french in over 5 years :D hahah! wiki :D

for question 1b) i why cant we just do this: (x-a)^2 = P(x) and then differentiate then sub x = a into the derrivative and we get 0... part ii, I got right... but vafa sent the solution to that :D

cool, i'll be back with questions :)

there was something wrong with the astrophysics question at the end.. grr! it was illogical :S

qui est jordi...? wow i can still kinda speak french

arggg i think i forgot to put in the values to give the constant of integration.. i completely forgot about that.. bah but i did reciprocal thing... pretty sure..

haha.. that was difficult.. missed out around 20 marks .. hoping for more than 70 percent.. probably between 50 - 65 percent though

that calculator actually has a little bug.. and you found it ;) it cant replay even thought it claims it can.
