Because a*2/5=1, after subbing in the x and y values into the general formula for a parabola. Divide both sides by 2/5 you get a=5/2.

Re: Need help to write out experiment with chyclohexene and cylcohexane and bromine w And btw, just a general rule of thumb: wash all components of your apparatus (scratch stuff like Bunsen burner, I meant things like test tubes, flasks etc :p) before the experiment. I lost half a mark for not...

We've started the HSC work in all subjects, just haven't done much. ... Yet. :o

Re: Olympiads Listen, I didn't even KNOW about acceleration till something like, last year. Very un-informed, wasn't I? :p See, I just never could've accelerated, anyhow :o

Gee, no need to insult his intellectual abilities here. f3nr15, it's totally your choice what subjects to pick. No one would *have* to like complex numbers :D

And sharpen your skills. Then you could very easily manage a band 6 :)

Re: Olympiads At least you could accelerate in, something. I wish I accelerated in IPT in year 10 or something, just to get some units out of the way. And Cosmology sounds so interesting x.x

That's actually the method we're taught to do it, in physics o.0

Yes of course, SS would know, since he's looking to be coming first in all his subjects XP

So that means a person who gets 89 doesn't get to do it, but one who gets 90 does. o.0 Why should there be such a cut-off line in the first place?

I assume we're talking about projectile motion in physics, not maths? :p Meh, still need to get really familiar using those formulas...even though we learnt them last year XD That really sucks :( We just have to sign this senuor privilege note ourselves and by our parents and we could cmoe to...

This is the product of 2x and 3x4-x. The derivative of 2x is 2, and that of 3x4-x is 12x3-1. So, by using the product rule, the derivative of the whole expression is 2(3x4-x) + 2x(12x3-1) = 30x4-4x :)

I meant that the marks and ranks would now be up for us, since we're starting year 12. <.< Therefore, not relieved. :S

They do?? ... Not Maccas again like the offline 3u class the other day, right? XD

You do that and I shall haunt you for the rest of your life :D

I knew it very early in year 1 that teaching will be something that I won't do in the future for a job :p ...Just can't picture myself, well, teaching, a roomful of kids XD

Actually, I remember seeing this grid thing outside the maths staffroom the other day. It shows you how many people got what marks in which classes :eek: ...I was very relieved to see that it was for year 12. :p ... Or maybe not-so-relieved, now?? <.<

Enjoy it anyhow, SoulSearcher :) SO tired yesterday cos I only had something like 2h sleep the day before :p Therefore, hit the pillow at 9pm last night and fell asleep pretty quickly, and fortunately didn't wake up in the middle of the night again :D Pity had to wake up earlier than usual...

Wow. Never knew that you could actually move from Std to Adv English o.0

You probably won't get Journeys as AoS. Just got my stimulus booklet, and it says, "for HSC 2006 and 2007".
