Can anyone recommend some visual texts for changing perspective of Australia?

Re: 回复: Re: How was your school day? We have no idea how hard your tests are. Maybe you could post some up? It would give everyone else some good practice as well.

umm ...that would only work if two co-ordinates were given as the length of the diameter, which they aren't. Try using the equation of a circle ...then sub in a few points, solve simultaneously

Did you do it? And if so, how did you find it?

This is exactly what happens to me! Don't worry, I have the shittest memory and I do pretty well at school. Just concentrate harder, and revise more often.

Porridge and maybe some fruits.

Yeah, Gosford High.

1:30 - 6:30

Why would you use trial and error? 2x + sq. rt. (6x + 9) = 7 sq. rt. (6x + 9) = (7 - 2x) Square both sides; 6x + 9 = 49 - 28x + 4x^2 Use the quadratic formula.

I'm going to do it! :)

Thanks!

Maths Advanced: 67.5/72 Maths Extension: 50.5/60 English Advanced: 16/20 Physics: 33/35 Chemistry: 49/55 Music: Yeah, dropping this as soon as I can ...no need to disclose that mark hehe

Yeah, it would ...just curious as to what sort of mark that would usually equate to

Hey undalay, do you know the required mark to get in for physics?

Hey, who here is currently training for the physics olympiad? How is it? Were there any requirements for you to participate? i.e. rank or marks?

( a^2 + b^2 + 2a^2b^2 ) ( a^2 + b^2 - 2a^2b^2) + c ( c - 2 ( a + b ) ( a - b ) ) ?? EDIT: First of all, is that what is shown in the answers?

Hey, did anyone sit this competition? If so, how did you find it? I thought it was easier than last year's one.

Yeah I'll probably try 4 unit: Marks and rankings for 2 unit and 3 unit are as follows: 3 unit: 98% - 1st 2 unit: 98% - 1st Yeah, I got lucky ... This will probably change when we get our next set of maths results later today.

Haha, it said on James Ruse's website that in 2005 the mean UAI was 99.25 ...so yeah I think more than 75% probably attain a UAI greater than 90.

Argh ..still have 5 half yearlies to go
