as it stands thats FALSE. for example, -2 < 3 but -1/2 is still less than 1/3 you only flip the sign when you can confirm that both sides are of the same sign

Your first line doesn't follow from the second.

This is actually quite interesting, reminds me of something called inversion: http://whistleralley.com/inversion/inversion.htm

BCom/BEc is for those who believe in a traditional four year education!

Unless ppl at your school talks about UAI omitting the first 2 digits.. as in "I got .25" or "I got .40"

Yeah we know you are clever :P As with your UAI.. I think it;s going to be around 94ish .. ofcourse it depends on how your classmates and you perform. I think by internal mark your teacher meant the moderated internal marks

you can put some random subjects in the preferences for now.. change them after you get your UAI As for the prediction.. it should be more than 80 unless some crap happens

You need to wait till she comes back to earth from planet mindreading

Short term potential: good medium/Long term potential: poor

depends on your school.. your teacher etc..

Prove that there is an explicit way to disect a cube into n cubes (perhaps of different sizes) for say... n>100 Prove that one can do the same with cyclic quadrilaterals, that is given a cyclic quadrilateral one can divide it into n cyclic quadrilaterals when n>100 Here's one which I don't...

To do this you would probably first want to express the position of the deck as a function of time, then solve for that equal to the level of the wharf. Basically you let y = height of the deck of the ship compared to the wharf, then y'' + ay = 0 (SHM) for some a. then you somehow solve it...

Maybe if you put the questions up, we can give the answers :P

Here's another more or less standard question: Assuming you all have an idea of what conditional expectation means. The conditional variance Var(X|Y) is defined as E((X - E(X|Y))^2 | Y) Prove that Var(X) = E(Var(X|Y)) + Var(E(X|Y))

It was clearly stated that the eigen values are distinct :P. The proof is very short. Care to give a new question? EDIT: I see what you mean now.. But then the word distinct will serve no purpose.

I think the Liberal party won't be happy about that :P

Erh.. not quite.. almost there, what you have is that if X'X + a*I is not invertible then X'X has a negative eigenvalue.. it doesn't rule out the possibility of it not having positive numbers or zero as an eigenvalue. Oh sorry by the way, ' is not exactly transpose.. it's conjugate transpose...

gman03 possesses an uncanny ability to make a timely reply to any post mentioning him :P:rofl:

yeah.. jsut make sure you work fast enough.. for the 3U exam.. it's 7 questions in 1.5 hours or was it 2.... man forgot :(

Not trying to be apologetic, but: I absolutely hate those kind of questions too, luckily my parents usually don't ask that. However, there might be other reasons for it, I have an aunt who asks my cousin the same question(I happened to live with her for a while).. I think partly it's there to...
