I think he is talking about this equation I've merely glimpsed upon lol. It goes something like: delta(H)=-mC*delta(T)

Electricity and motion would probably be the two most important prelim topics towards HSC physics. I recommend you learn them quite well. The other two not as much.

I know all that except molar heat of combustion. We haven't been sticking to any particular topic, it's been more going from one topic to another and yeh pretty crazy shiet.

my teacher is going pretty damn slow and so im getting worried. we have been switching topics from one lesson to another so I know some stuff from all the topics. but we are only just formally beginning the topic metals. should i be worried?

I just had a look at the Harder 3U section and in the first question it is said that: a1,a2,...,an are positive integers yet a1+a2+...+an=1 This can't be. Do you mean a1,a2,...,an are positive?

Re: HSC 2012 Marathon :) shitballs I just got on the forums again and I see this..

my exact thought

Re: HSC 2012 Marathon :) oh yes of course. lol, I got confused when barbenator said the range was y>-21/4 and didnt bother working it out on my own..

Re: HSC 2012 Marathon :) With this question, how come the domain of the inverse function isnt identical to the range of the function? The range of the function is y>1 and the domain of the inverse function is x>=-21/4

Re: HSC 2012 Marathon :) Cbf getting a piece of paper and answering this right now but just to help out you have to restrict the function to a particular domain for there to exist an inverse function.

yes yes yes!

It's pretty funny actually.

coming to the meat roughly 9 hours late

just trying to stop a younster making the mistakes I did..

knew this was comin

It's probably best you try to get to know everyone as everyone is trying to get to know each other, relieves awkwardness throughout the day. so yeah. get there early dude.

They're awkward with people though.

Just stay home then..

lol

shit seanieg is comin'
