Re: Wow, fuck that part (ii). I thought it was just dV/dt = dl/dt x dV/dl

no :(. I just thought i must have been wrong. What was the value of the time?

You were supposed to get a negative time???? I got the negative time and tried to figure out what was wrong but couldn't see anything so i just left it.

I reckon i'll end up on 45-50/84.

Re: Holy Fuckaroni Ended up rushing too much at the end. Did reasonbly on Q 1-4. 5,6 and 7 i did poorly.

I got absolutely smashed. Went alright up until q5 then got hammered.

That's the plan for me too. Just hope to god that i can get out the projectile motion question. Sometimes i can ace them but other times i just can't figure em out.

Bound to be a couple silly ones throughout. I forgot +c as well on the hence integrate question in Q4.

After looking at the solutions thread. 107-110/120. I'm happy with that. Couple silly mistakes and question 9 messed me up a bit but the goal was band 6 so it's all good.

The answers in the first post for question six are correct. The area from 0 to 2pi is 8 and the value from pi/2 to 2pi is -2. Value can be negative, area no.

I screwed this one up, made a super stupid mistake. But how many marks do you think i'd get for drawing the curve above, except i started it from below the axis, and the asymptote was above the axis. It still cut at 1, had stat point at 3 (although max), and asymptote.

A1 = 29227(1.005) + M(1.005) A2 = 29227(1.005)^2 + M(1.005)^2 + M(1.005) = 29227(1.005)^2 + M(1.005 + 1.005^2) A3 = you get the point An = 29227(1.005)^n + M(1.005+1.005^2+...+1.005^n) = 29227(1.005)^n + M(a(r^n-1)/(r-1)) After 240 months An = 800000. So solve the equation when n =...

You will lose 1 mark, because the marking criteria will say 1 mark for correct solution.

fuked up on 4(e) but i realised that when i first looked back over the paper. Will still get 1 mark for 1 correct inequality. Other than that everything looks good. Confident that i am 100+/120, after seeing this i think my mark should be up near 110.

ahhh alright. I reckon i'll be pretty lucky to get E4. But who knows. Should get 40+ anyways.

You should still pick up a mark because the sequence would still be the same, just the wrong value in the end. You would have just ended up with the amount of cents, in dollars.

I'd like to get a top band though. What would 70% raw scale to? I've been getting like high 60s (percentage) in most past papers. 2008 was just a bad one for me. I'm about to do 09 now.

When you worked out r in terms of P that gave the max area in (iii), you get r = P/4 (4r = P). But P= r(theta + 2), from (i) 4r = r(theta + 2) 4 = theta + 2 theta = 2. I didn't even realise you could use part (i) to work it out. I forget exactly how i did it, but i used the equation for...

110. Got fuked in question 9, rest were good.

I've been getting just under 70% for most past papers for ext1. Just did 2008 and got fuking raped.... Not a big confidence booster. Only got 55% =/. I have been aiming for 70% raw and have been doing that in other past papers. What has 2009 and 2010 been like compared to 2008, if anyone knows?
