Re: 2012 Year 9 &10 Mathematics Marathon For i) OQ = OP (radii of circle) Therefore, triangle OPQ is isosceles. \alpha = 2\beta (angle subtended at the centre is twice the angle subtended at the circumference by the same arc)

Isn't Australia coming 11th? Well, maybe that was the case only about 13 hours ago.

Re: 2012 Year 9 &10 Mathematics Marathon You are correct. Was this your working out? Let x = height of triangle, hence 2x = base of triangle By triangle formula: \frac{2x^2}{2}=36 x^2=36 x=6 Reject - 6. Now by pythagorean method on a right angle triangle, let y = hypotenuse: 6^2...

Hmm, my school doesn't make it compulsory to do work experience. We only do it if we feel we want to do it, where we have to go through a process with the school advisor.

Just use this again: http://mathim.com/bosbrawl

Do you wanna try the MathIM chat from yesterday? It could be easier.

Sure, I'll try and join you.

I'm on right now and I'll add you.

I don't think so. I can start playing a bit of ge007 right now if you're ready as my parents have finished using the television.

Yeah, just use this thread :P

Don't worry too much about the question, we're all human. Was the courier question, Q 26. in your paper? You could still possibly get a HD after this error as I did the senior paper you guys did and I couldn't answer like 8 questions. Good work. :) Mhm, I think I managed to solve that...

I might scan up my solutions if I can. Typing it all out on LaTeX is time consuming.

I think optometry is accessible only in UNSW if you're talking around these regions. My sister is an optometrist from UNSW and she has told me herself there wasn't any other career she'd rather be in. Of course, this idea of enjoyment varies from person to person. Take some work experience up...

You guys can start a game first.

Will do. I will be playing right next to the computer. I might be a little slow on controls because I haven't played in a while, but I imagine it's the same for most of us. Nice idea with the chat room, seanieg.

Pretty much what I did. The idea of 'geometric progression' was made to throw off people although it isn't really that wordy.

I think I talked to you at the study meat for a while. Mhm, you mentioned he was a music scholar.

Everybody get your game faces on for tomorrow at 1pm-3pm:
