I'm assuming that you are not talking about the limiting sum of a geometric serie, just simple geometric sums. The proof for the sum of geo series is simple. Learn it. You'll realise that the absolute value thing is just out there to confuse you and is redundant. Both sum formulae produce the...

Ever tried ropes?

I recently acquired what I believe is a short homemovie featuring what I believe is naked Jessica Biel taking a shower. It's probably just a look alike but damn she looked pretty damn hot. Really good look alike too.

I use Bitlord for my everyday torrent needs. It's configurable, portable and neat. I tried lots of other clients including Azureus (which didn't recognise my open port) etc.. I find that Bitlord works the best on my machine.

Ok thanks. I'm a tool. I've got 6 hours of exams tomorrow but then nothing for a week so I'll use that week to brush up on my trig.

OMFG! My class hasn't done any case studies wtf! God I can't believe how stupid our teachers are. I don't think they even mentioned anything about case studies :(. I've got 6 hours of exams tomorrow I'm screwed for business studies :/.

You guys are lucky then because my trial was absolutely impossible. Not a single straight forward question. Every single had some trick or something to stop you getting the right answers... I've done hard exams in the past but this one was the hardest by far. I struggled.

Thanks. What about this integration(I): I (sin 2x)^2 dx It was in my trial today and I didn't know how to do it because of the 2x. Had it been x I could have simply substituted the trig identity (sinA)^2=1/2(1-cos2A) but what should I have done in this particular case?

Ok I've found out that it's a double angle trig formula but it is not in my math book. Someone mind proving it?

Can someone tell me where this identity comes from and if it's in the 3U course + proof (sinA)^2=1/2(1-cos2A)

Not all schools have to resit it. It is up to the school's discretion. The deputy principal informed us this morning that our school is not resitting it.

Such low standards...

True, I too think that just the HSC should count. Although I rekon that it is possible that some people cheat the HSC too. I mean it's possible that teachers/tutors tell some of their students what is in the test. Highly unethical but I'm sure that some do. Bloody cheaters.

Shit i have to do all those chapters that i "skipped" lol. LOL I still haven't done mathematical induction. I've always skipped that chapter in my revision.

That isn't very fair in my opinion. It is possible for people to improve over the holidays. Especially in english were it is very possible to memorise most of the material and simply adapt it to the question.

Yeah hehe my mistake. According to what I've read in this thread it seems that my exam wasn't the cssa :/. It's too bad because I would have really liked to be able to compare with everyone else... Lol the funny thing is that my 3U class has finished the entire 3U and 2U course but all...

The deputy at my school has informed us this morning that we do not have to sit the exam again. Some might say that's fortunate but I would have been thrilled to sit it again, since I found my performance in the original one rather mediocre :/.

I just finished my trial 2u exam! I 'm not sure if it was the csaa. I thought they said it would be the csaa trial exam but the cover had my school's name on it. Maybe the school rebadged it :/. I don't know. Anyway I thought it was a pretty simple and straightforward test although I would've...

I usually get between 4 to 6 hours of sleep. It is not uncommon for me to go to bed between 1 and 3 AM during the week and 3AM+ during the weekend. I'm used to getting little sleep. In year eleven I had all nighters every weekend. I find that it does not drastically affect my performance during...

I found it excruciatingly hard compared to past ESL HSC examinations. Timewise especially. Completely ran short on time, I did not manage to start the last question from section 1 (that's 7 marks gone). My essay was barely 4 pages and I did not have time for a conclusion. Because I was so...
