Nevermind :( I'm an idiot!!! Expand -2(16+t^2) = -32 - 2t^2 .... thats not the same as 32 - 2t^2 is it. My bad.

Hey! Great job, thanks for the solutions! One question though. For question 5 b) ii) (which leads me in to getting iii wrong). Differentiating velocity we get: 2(16+t^2) - 4t^2 (please disregard the bottom for now) = 32 + 2t^2 - 4t^2 = 32 - 2t^2 => -2(16+t^2) on the bottom we have...

Let me put it to you all this way. My scenario: a) Answered it b) "" c) Kinda answered it well d) Got it (I hope :D) e) WTF? Only point I made was he tells us that we don't have to go out looking for journeys, that they might come by chance... Then I wrote utter BS! (was my point even right?)...

Thats f!cking disturbing!

Yeah same, I was a bit nervous so I couldn't get any sleep. Ended up "chrashing" (gotta be correct now ah... Only a couple of hours till thy exam??) at about 2ish after trying to put myself to bed for 3 hours. Best wishes all!

Thats the shizz mate... Good luck with it!

my apologies, what I meant when I said band 5/6 UAI is the range, I didn't actually mean that you get a band UAI

Rightio... Thanks. I don't get it?

I don't understand this 'predicting' stuff... Does anyone know how the HSC marking REALLY works??? I've heard stories of people doing ABSOLUTE CRAP during the year, doing well in their HSC exams - band 5/6 UAI (presuming they got 80's and 90's in their exams though). I hope I'm not coming...

What happens if theres only classes of max 28... Most of my classes only have 5-8 people in them!

Thanks so much!

Hello, I'm tryingto figure out the integral of cos^3 x...and I cant get past the first step! Could somebody please point me in the right direction after: (1 + cos 2x) cos x dx Thanks so much for your help in advance

Awesome, I'm hoping Australia beats Japan (statistically speaking we will :) ), I'll be on the edge of my seat, for sure! Just wondering, if Australia do make it through to the finals, will there be a screening in the City (Sydney) or would we all rather staying in our cosy homes/pubs/clubs...
