    88 did align to 97 last year according to the Raw Marks Database. Aligning might change though of course.

    I know someone who got busted for cheating in the hsc

    If you get 0 for a subject, doesn't the person who comes last internally also get a 0?

    2014 HSC Extension 2 Maths Carrotsticks' Solutions

    For the argand diagram question I didn't explicitlywrite that the angle was pi/4 but I did show that the boundary lines passed through (1,1) and (1,-1). Is that alright? Also how pedantic do you think they'll be about the graphing question afterwards (x^2-1/x^2)? Will they deduct marks if the...

    Why do people think MIF is bad?

    That's the thing. Selective schools don't use maths in focus, or at least the top classes don't. If you wanna be the best, study like the best. In other words, don't use Maths in Focus.

    I doubt the markers are that pedantic. It's already given that M is on PQ so you shouldn't have to state it again.

    2014 HSC Extension 2 Maths Carrotsticks' Solutions

    Theoretically, wouldn't there be a certain f(x) for which 1/f(x) would be smooth at x=-1? In that case drawing it disconnected would also be wrong in certain cases. Since they don't show any y values, its impossible to deduce which case it is, so I don't think they should penalise us.

    Predict Your Raw Mark

    98-99 Cross checked mc and numerical answers with yours and the proofs I'm 99% sure are correct. Definitely lost 1 for multiple choice (q9) and I may have lost one in the integration question in 11 (may have accidentally wrote 1/pi^2 instead of 3/pi^2). Anyway what's your expected raw- mreditor.

    State Rank Mark

    What raw mark would you need in today's exam to get a state rank? I know someone with 98 raw, 1st internally, came 4th last year. I'm guessing 96 or 97?

    I hope for my internal's sake that mreditor gets full marks.

    I finished with around 15-20mims to go so it was a relatively easy paper. Expecting 99 raw.

    Section I: Multiple Choice

    DABCCDBBBD Pretty sure they're all right except for 9 which should be A (silly me-gg first in state) For D, I let F(x) be the primitive and worked from there

    Pencil?

    You use black and blue pen for writing, and pencil for drawing, although I doubt they'll penalize you if you do some writing in pencil. The paper is scanned anyway so I don't think they'll even be able to tell. Just make sure its dark enough for the scanner to see it.

    Hertz' experiment: AC or DC power source?

    Hertz fed a low voltage DC power source into an induction coil to produce a high voltage, high frequency AC which he then fed into the transmitter.

    I'm not sure if you've heard of this, but have you tried bored of studies? It's like the hsc discussion group, without the retards.

    0.16 (A) is what you get when you divide Load over effort. However, the machine isn't necessarily 100% efficient so VR!=MA so you have to find VR on its own. This is basically (2*170/700)*(20/50)=0.19 which is B
