the x-coordinate of the xy plane

It is its own inverse, ie f-1 = f

My marks entered into SAM gives 0.05 lower than what I actually got.

correct .

Yes, Mathematics is the 2 unit advanced mathematics.

I sort of wrote a template for mine, i didnt memorise any area in particular as an actual essay, but i did memorise the form that my essay would take and where all the generic information that would be part of any question they asked would be written.

Why is getting <97 worthless? Its not like you need to ace 4 unit (or even do it) to do well in future mathematics.

"A course loading of 0 means that the candidature of the course was average, and hence that the course had average scaling. Courses with positive loadings had above average scaling. Similarly, courses with negative loadings had below average scaling." To me, that sounds like SDD scales above...

Look at his profile, theres a link to his IMO profile with his name, then just search for his name on the bos site ;)

You use the general formula: Tr+1 = 19Cr 3r (9x)19-r So Tr = 19Cr-1 3r-1 (9x)18-r Then just divide it and youll get a) For b) if they have equal coefficients then the ratio of Tr+1 and Tr will be 1, so use your answer from a), equate it to 1 and solve for r

If he's anything like some others who top that state, it probably wouldnt be as much as most people would think.

Mr Hong Kong answered this question before:

Bankstown Community College is probably one of the best places in terms of HSC arabic, im sure they'd be pretty good all round though.

No, doesnt look too bad though. Wouldve been good to be able to compete in it. Probably wouldve done it in C.

If I could give one piece of advice for 4 unit i'd be repeating what Slide Rule said above. It cost me dearly.

its all prelim trig.

A much funnier parody of the hsc 4 unit exam was made last year (or the year before?), unfortunately i cant find the link to it :(

I uploaded them. Theres some 150 files to go through, so it usually takes some time to look through them.

Even so, its great practice for first year uni maths, where first principles are your friend, especially in double variable calculus ;)

I think you'll have more luck in the VCE forum, i recall they were having a conversation about calculator programs before.
