    Trial Question

    +1 to what the other people said, but you won't often get a question so vague. Usually it will allude to a specific technology/technologies, often semiconductors or superconductors.

    HSC Music 2

    I didn't do music 2 but I'm pretty sure that in this context, 'classical' means a similar thing to 'art music' (ie 'serious' music) rather than specifically from the Classical period.

    How hard is 2U Math in Year 11/12 compared to math in Year 10?

    2U maths in year 11 is definitely harder than year 10 maths, but not by such an amount that it's difficult to do decently in it. As long as you consistently practice the skills you're learning, you'll most likely be fine

    Help me decide :P

    Give 2U maths a try; if it really doesn't work out then you can drop to General. But if you don't like maths and certainly are not going to do a STEM course at uni, then consider doing General in both years 11 and 12.

    Matrices question

    What's getting me is that we need to use the n=2 case in the inductive step, but (as far as I see) there's no guarantee that the statement holds true for integers for the n=2 case (like, what if all the entries of M are irrational?)

    Matrices question

    Kingofacting has helped me to prove this for real numbers a_n and b_n, but not integers... can someone shed some light?
  12. porcupinetree

    need suggestions plz

    +1 to all of the above. Just focus on doing well in the subjects that you're doing; no point doing extension subs if you're not going to do well in them.

    Re: USYD Chatter Thread - Semester 1 2016 How's everyone's timetable for next semester looking? Somehow I managed to get mine down to 3 days (especially surprising considering that I'm doing a science degree)

    The Code Marathon.

    maths

    For (a), use the fact that distance = speed*time to figure out the distance of each family from the intersection. Then use Pythagoras' Thm to calculate distance between the two families For (b), differentiate the equation in (a) wrt t, and find the value of t which will give a turning point...
