    abc conjecture proved?

    i think he means 2(x^3+y^3+z^3) = > x^2y + y^2x +.....+ z^2x = > xyz(......) = > 6xyz then let x = a^1/3 and bingo.

    Magnetic Flux is a scalar quantity.

    Magnetic flux is said to be a scalar quantity, yet it is measured bi-directionally, i.e. the direction in which direction the flux cuts the coil. In this case, is it just a simple scalar quantity or is it a vector (or something inbetween), as it has direction? the reason I am asking this is...

    abc conjecture proved?

    The one thing i got out of these documents is that S.Mochizuki can lift. so dont ask him if he even lifts, because he obviously can. "[CanLift] S. Mochizuki, The Absolute Anabelian Geometry of Canonical Curves, Kazuya Kato’s fiftieth birthday, Doc. Math. 2003, Extra Vol., pp. 609-640."

    yes they can, but just argue and they should change it

    acidic env. multiple choice

    its because when a base is added to a strong acid, the hydronium ions react directly with the hydroxide ions. In a strong base is added to a weak acid, firstly the hydronium ions will react, but then le chateliers principle will kick in causing the system to react and create more hydronium ions...

    ATAR Estimate

    tbh i dont think u need an estimate as you know more about this than most others and know the most about your school. this is the exact same reason why i dont ask for estimates

    Good integration question to try

    iirc wanga, it was x^2-x but same way around it anyway. its a very good question

    acidic env. multiple choice

    a titration causes equilibrium reactions to go to completion. You don't have to worry about whether the molecule is fully ionised or not.

    Really shit at Prob/perms/combs

    for the tennis ones, I think there is an easier and more efficient way IMO. a) set 1 person to be paired. There is 3C1 ways of picking a partner, the other pair comes as a result, hence 3 ways b) again, set 1 person, 7 partners, next set another, 5 partners, again another, 3 partners, and then...

    USYD colleges?

    1) Yes. Its quite a bit per pop, like $100-200 and yes you could shop around for a scholarship but personally I would be going to the one you like the most 2) I have stayed in the womens college myself and it is really nice in terms of grounds, food etc. I'm not really sure about the misogynist...

    Ind, the teachers say don't do it because they want to conserve their b6 ratio. If you are picking subjects for ATAR purposes (are you? because otherwise my argument is invalid) then you should take it no matter what. I have faith that A) you are better than Shadowdude and B) you can just learn...

    Atar est based on trials

    this one is a toughie actually my best bet is 84

    how hard is it to get above 90 scaled assessment mark for phys chem and eco?

    lol dude they arent false rumours. If I went to james ruse and came first in 3u maths, you cannot tell me that im going to be expecting below 100. Trends are quite consistent for most of the top rank schools, and if they do vary, it is very slightly, so deswa1s statement is quite accurate

    estimate my atar!

    99+ is achievable, just difficult with your english ranking
