    A few random tips

    Personally, I wouldn't go with that method, but each to their own. And also, I don't agree with that notion that it's designed so that no one gets 100. I can guarantee you with 100% certainty that i lost my marks not in question 9 and 10, but in question 2 and 3, one due to a slight rounding...

    question 9 and 10

    I couldn't have said it better myself.

    trig question

    I was wrong in that proof because I just assumed that the steps can be reversed without directly doing it. For this question, basically, you cannot prove something is true by supposing it is true and showing this assumption implies something which is obviously true. You have to check that each...

    Usyd scholarships

    I was exactly the same as SeDaTeD, got the acknowledgement and then rejection one for that main scholarship. Then I was given the IT entrance one a few months into uni.

    trig question

    Well you could always replace it, assume it isnt true and prove by contradiction.

    New Mod!

    Greetings all, I would like to announce that I have stepped down as mod of both maths and maths ext 1. It's been a great one year or so, but i felt it was time to leave. Replacing me is Slide Rule, who I thought would be the most qualified for the position, play nice ;) I'm sure he'll do an...

    Parametric Formulae

    If you want my opinion, I wouldnt test the marker in an exam. If you do it the full way, you can be certain of the marks. However when doing questions at home its really up to you. As far as I can see from a quick look at the syllabus, there is no mention on what you can/cant assume, other than...

    complex number question

    afaik, you can quote that complex roots come in conjugate pairs without proof (correct me if im wrong, i didnt do 4 unit). But if you want proof, my post above shows how to do it, as did KFunk's.

    For a quadratic, yes :p

    complex number question

    You can prove that complex roots come in conjugate pairs: Take P(x) = a0 + a1x1 + a2x2 + a3x3 + ... + anxn If you assume z is a root, then sub z into the RHS and make the RHS = 0 a0 + a1z1 + a2z2 + a3z3 + ... + anzn = 0 Then take the conjugate of both sides, manipulate using addition...

    MATH 1903 Lectures

    I dont really like the 8am ones, but if my timetable was the same as my current one, 4pm lectures would give me with three days of huge gaps, wednesday - 5 hour gap, thursday - 5 hours, friday - 4 hours. So I'd much prefer the 8am ones, which only mean getting to uni an hour earlier every day...

    trig question

    ^Mr hong kong just showed you how using both LHS and RHS is a good method. Sometimes you come across questions where it is almost impossible, if not very hard, to prove both sides are equal without manipulating both.
