So what would the shuttle be propelled back, instead of being captured by the planet? Is it just the engines inside at work?

Yep, chose IPT cos that's the only computing course on offer, and now hating all the theory work :mad1: The practical stuff eg. website is good though! :D Main reason I chose it - I like working computers :D

Nope I'm not too late :D Entry applications close around 5 June or something :) Read the previous posts, I'm not referring to the one that was already held on 11 May :p

Is this maths? Looks morel ike chem or something :p I don't know this formula, and I'm just assuming here that t is time measured in years, M0 and k are constants, and e is the original mass measured in kg. (Which is not necessarily correct :p) From this, sub M=200/2=100, e=200, and the...

And I started to solve line equations for a couple of chopsticks the other day when two of them lay perpendicular to each other with others scattered on top of them. :uhoh:

^But then they would've gotten a pretty decent rank for internal assessments and thus a good mark internally which would then count towards 50% of their UAI. fireice, so it looks like you're sure these people are letting their tutors do their assessments? But I personally wouldn't do anything...

...I'm still struggling with my weekly French listening skills exercise and feelingso dumb :p

lol I remember my maths teacher went through the whole 1/3 thing with the whole class trying to get ppl's heads around it :p Weirdest things happen at infinity...O.O

Does it have to be proven by induction? :p OK here goes... When n=2, 122=144 >72+52=74 - base case proven; Assuming 12n>7n+5n, 12n+1 =12*12n >12*7n+12*5n Since 12>7 and 12>5, 12*7n>7n+1, 12*5n>5n+1 -->12n+1>7n+1+5n+1 --> Induction complete. Or, you can just prove it directly for...

Goodie. 'Cos that APMO really murdered me. :p

Your friend's method comes directly from the theorem that the sum of all exterior angles of a regular polygon is always equal to 360 degrees.

Because, (say the internal point of division is C and the external point of division id D) AC and BC are two intervals in opposite directions whereas AD and BD are in the same direction. See the diagram attached (note: not to scale :p)

Erm...what exactly is needed to be proven? The second part of the sentence seems to be just the description of a subject, not a complete statement :confused:

We're up to Metals too. Ahh not good, stomachache throughout the chem prac this morning which counts for 15% >.<''' Even as of now I am hunched here in front of this computer bearing the annoying pain :/

Exactly what my assessment task for the Macbeth unit would be :mad1: Except it'll be in about 5 weeks, just started the unit today :p

Never heard anything about it at school x.x How does the difficulty compare with AMO and APMO? Or the AIMO (ok maybe not this...considering only two questions are free responses :p) and the Senior Contest? EDIT: There seems to be another maths comp held by UNSW, and it was already done on 11...

2Zn(s) + 2NaOH(aq) + 2H2O(l)--> 2Na[Zn(OH)2](aq) + 5H2 (g)

Not exactly like that, but the two oxygen atoms SHARE two electrons between them ie. two electrons from both oxygen atoms - total of four - orbit around the nuclei of both atoms. It is not a polar bond between the two oxygen atoms.

Of course. But parent-teacher interviews are something that I'd definitely not miss :p

Finally the end of a week of frenzy. Making the English website was fun (OMEGEE!! Another website is born!), but definitely not chasing down ppl for their articles to be put onto the website. :mad1:
