umm, for 11. b) ii) argz = pi - arg(1/sqrt3) = pi - pi/6 = 5pi/6 not 2pi/3

umm, MCQ 2.A? Isn't it? B) doesn't work cause, for example, if you sub it in, (-4-3i)^2 = 16-9+24i = 7+24i not 7-24i. Or if you prefer the longer method, of equating real and imaginary components/completing the square, x^2-y^2 = 7, 2ixy = -24, xy = -12, by inspection, x=4, y=-3 or x=-4, y=3...

Hello, I'm trying to find the past paper that has this question. Thank you!

Well, I guess I was doing it wrong. :)

That one year when all of the NAPLAN results were misaligned and Maths skyrocketed... (I don't think that it really corresponds to the HSC cause no one really put any work into it, it was like a walk in and walk out exam)

School rank isn't relevant to your HSC marks but it can be representative of the quality of the cohort which can influence your HSC scaling. When you compare a cohort from Ruse compared to a cohort from a rank 500 school, the stronger cohort (Ruse) would perform better in the HSC, thus has...

Definitely, I know two people, one that was ranked ~12th internally at Ruse and one that was like 4th in internals that got a state rank

And less practice really goes into 3U

Well, I keep stuffing up 3U (can't get 100) and everyone always gets like 100% so it's very hard to catch up.

nah, this is for another friend (sorry about all of the estimates guys)

I guess English needs a lot of work to do... T.T
