Are you using it to display an image? IE is it turned on? If so you have to have some kind of certification from an electrician to say it wont kill the markers. Otherwise there shouldn't be any problems, grass is a no-no with sculptures but if it's that plastic kind of screen I don't see why it...

Out school gave us only one past paper so far, and for the rest you should be able to look up most of the images on google. Otherwise I know there are sample papers in the HSC revise VA in a Month book. Don't be too worried (:spzz:) about having heaps of actual papers, you can always try taking...

EDIT: Hmm. Ah I remember: a is taken outside the normal domain (ie not on the curve in our graph). Hence y <= 1, otherwise it would be on the curve at y >=1. Theres a graph of the inverse http://www20.wolframalpha.com/input/?i=y%3D1%2Bsqrt%284x-7%29

To solve you find f^-1(x) which is y = 1-root(4x-7), then sub f(a) into the x value there (1/4 and 4 cross out in the process): f(a) = [(a-1)^2]/4 + 7 f^-1(f(a)) = 1-root(-7+7+(a-1)^2) f^-1(f(a)) = 1-(a-1) f^-1(f(a)) = 2-a

Man you need to post the actual question, I have no idea what you need. I can prove that using Induction which is related to series in the course, otherwise I have no clue what you are trying to do.

Same thing:)

I don't do any of the sciences, and am glad :)

jetblack does this, however by saying z=2iTan(pi/10) you assume a value for theta, hence can simply sub the theta value into the RHS and find when Cos(5@) = 0. I think doing the expansion would take too long but would show it's a root yes

Iv'e always taken the air resistance as mkv in this case, that's at least what our teacher showed us. But there are questions that have the m's in there during the integration, so never crossed them off unless you can.

If they are all part of one piece, and should be exhibited together then it sounds more like mixed media. A collection of works can be arranged differently but are part of the same concept. Choose whichever is more suited to the conceptual nature of the work.

It's a bit like that isn't it? Thankfully I have done a few more then you..

http://www.padowan.dk/ 100% program called Graph, it just does exactly what you want and is all you really need for quick reference. It does some nifty calculus stuff too. For everything else Mathematica.

Re: 回复: Re: holiday study The little break coming up is the only *real* break you get under after your HSC. Enjoy it while you can.

Going for a walk or other exercise is a very good idea, you really do need a balance during HSC that way any free time you spend will be guilt free knowing you have done the work for it. The other thing is not to get sick, that is something to worry about-exercise and eat well. Don’t be afraid...
