You're welcome :) ...? So you mean...it only works for some values?

Ahahahaha :rofl: That would've thrown them though, don't be so cruel :p

... Doesn't ring a bell :p

More like, match the expectations :S

May I give your own username to you as a piece of advice? :)

So "Revise in a month" is the name of this series of study guides? o.0

I say it's basically memorising loads of texts and attempting to put down as much as you can during the exam :p

Just a note, when I mentioned the kth number in the nth row of Pascal's triangle, I take the row that's notionally the 1st row (the one with a single 1) to be the 0th row, and the term that's notionally the 1st in each row (the first 1) to be the 0th term. This then allows representing Pascal's...

I'm not very good at combinatorics, but I'm gonna give it a shot anyway :p a) To get x^3, you need to multiply two terms of x^2 with one term of -2/x, and when you multiply the three brackets (of x^2-2/x), there are 3C2=3 ways to get a term of x^3. And since x^2 * x^2 * (-2/x) gives x^3 with...

*points out of the window* :p

I wish I could sleep in some day. Any day. Provided it's a school day, I sleep in during the weekend anyway :p Meh, now in period 8 of IPT while most of the year 12s go home. Pah. Why does IPT have to be off the lines. I wanna go home x.x

Re: The best physics textbook Oh good. Cos I think the textbook my school gave me is Jacaranda. ... I think. *checks*

lol, weren't these people trying to rewrite the rules of Einstein's Special Relativity? Something called "Very Special Relativity", uhh...very original name...:p

Wow, have you done Module A yet then? I think my school's doing AoS, then Module A, a bit of Module B then Module C, and then the rest of Module B. Yeah, weird. Or maybe they're just trying to spend more time on King Lear. You could pick up ext eng in year 12? Didn't know that you could do...

Hey, look, I've *really* stuffed up my first assessments, and that is markwise, and I'm not "giving up" and just let the marks slide any lower. Pull yourself together, man. It's not even like you've actually already got bad marks for the assessments. Don't just say that you're gonna give up...

Ooh, you guys have had muck-up photos, already? I don't even know when's the "normal" photo day for my school. Hum.

Uhh...The Time Machine? (Currently analysing, or desperately attempting to, that film to bits @.@)

Meh, my day today and tomorrow probably wouldn't be very interesting, but I did go to that Discovery Days thing at UoW yesterday. It was...uhh, pointless, quite frankly. Don't think it gave me much insight at all...and I had to get up at 5:30am to go there. Pah. I think I probably would rather...

Ahahaha, that was kinda the point :p

Uhh, I think you'd need to fix your questions... Huh? What exactly is BC equal to? Also, since there are only four vertices...this "triangular pyramid" is a tetrahedron, right? :p If I could take that you meant BC=5m, and BD=11m, then just use cosine rule on triangle BCD to get angle BCD. And...
