    Mathematics Extension 2 - 2016 Post-HSC Exam Thoughts

    What's everyone thinking of in difficulty in terms of previous years? Personally I found that Question 16 was slightly less accessible, but apart from that not too bad overall. Edit: Also, what do you think was needed for an e4?

    Degree of ionisation

    Sorry to start the thread up again, but just to point out an error. The relative concentration of each of the products (bar water) would remain the same (the concentration of the species in the above equilibrium would be diluted by the same factor). Hence, it isn't the fact that there is a...

    Can you give a better solution?

    Yeah I was thinking F, but wrote down E, my bad sorry. Addition by E would've formed the point B (w2).

    Can you give a better solution?

    So I've got this complex numbers question from the 1991 HSC Paper. I know its an easy question, but was wondering if my answer could become any simpler? i) is easy ii) i said put multiply E by i (rotation anti-clockwise 90*), no multiplication by factor c due to square having the same...

    Complex Numbers and Conjugates

    If you have an equation that is true, if you take the conjugate of both sides is it also true? For example, take z to be an imaginary number. az^2 + bz + c = 0 Now the question asked to prove this true for the conjugate of z. Am i justified in doing this? Also, are there any other...

    Extension 2 Inequalities

    Hi all, Just wondering whether for an inequality question, that in proving the inequality, it is sufficient to work backwards to obtain a solution that cannot be refuted (e.g.a square number is greater than or equal to 0). If not, is there any advice you could give me on how to prove these...

    Extension 2 Reference Sheet

    Hi all, After looking through the 2016 formula sheet that got released by BOSTES earlier in the week, I found there was no formulas listed exclusively for Extension 2. So just curious, is the formula sheet (for math extension 2 students) merely there to provide support with memorisation of...

    Analysing Attitude = English

    Hi all, I was just wondering what the best way to go about analysing the attitude of a text is (in relation to change if that helps). How would you go about this, and with what evidence/textual features? Thanks in advance.

    Parametric Equations

    Hi all, Currently in Year 11 and doing extension math. When doing parametric equations, is it better to derive the equations or try to memorise them? Thanks in advance.
