    UNSW Chit Chat Thread

    Re: UNSW Chit Chat Thread 2015. Actually logs of negative numbers are not undefined. The only point where Log is undefined is z=0. But Log z has a discontinuity along Re z < 0 and is not analytic there.

    is MX2 necessary for Chemical Engineering

    ...just checked it. CVEN2002 is half numerical methods and half computing. Chem Eng does basically the same thing, but it is labelled MATH2089. Anyway, as people have said, MX1 is fine, but MX2 is better.

    is MX2 necessary for Chemical Engineering

    Isn't CVEN2002 really a maths course? Or at least half stats?

    missing a tutorial?

    Maths...the only time they really care is if you apply for special consideration (if you were sick for the final say). Even if you miss the final for good reason they might not give you another go if you have been failing (< 40%) or rarely turning up.

    Difference between Science, and Adv. Science degrees

    First comment. The difference is really between a pass maths degree and an honours maths degree. The honours degree contains significantly more maths, not just because of the extra year of study. Lots of the maths courses are run at two levels, Higher and Ordinary. Entry basically depends on how...

    MATH1231 or MATH1241, difference?

    I'm guessing that your tutor was talking about exam marks not final marks. It isn't possible to get 100 after scaling in 1131.

    MATH1231 or MATH1241, difference?

    ...not what I heard. The top mark in 1141 was 99...definitely less in 1131. In any case there would be lots more scaling for a middle placed higher student than a top one (who probably got nearly full marks anyway). Somehow the higher scaling means that the maximum mark that is possible in 1131...

    Failed a few Courses :(

    You are better off doing them this session rather than waiting until next year. You can do both in session 2. You have probably already been unenrolled from math1231 and phys1221 so that would make room. You can do those over the summer if you want to catch up (dunno if you can do both at once...

    scaling/moderating marks?

    No, they will scale down. In Maths they'll scale you down if you do very well in an ordinary level subject when there was a corresponding higher one running (to be fair to the people doing the harder version). I think that the university has guidelines about how many HDs, and DNs too so that...

    Need Advice please! Math 1A and Math 1B

    MATH1A only runs in S1 and S2. MATH1B only runs in S2 and over the summer session. Changing your enrolment shouldn't be a problem any time up until the first week of session, except that you might find that the thing that you want to change to is full up or else has only bad tute times.

    MATH 1151 Question

    If the calculation had ended up as x ~ 1.5 that would mean that the number was 10^1.5 which is between 10 and 10^2, and so has two digits.

    MATH1131 vs MATH1141

    I think they have to do one first year maths in optom. If you just wanted to pass then you could probably sleep through a fair bit of 1131, but it sounds like you want to keep you WAM high so you'd be better of doing a bit more work and getting the scaling for 1141. Go to some lectures of each...

    University degree

    Not sure why you say that? More people at UNSW do pure honours than applied or stats. Some pure maths is much better to do at UNSW (like functional analysis or combinatorics) and some (like algebraic topology or differential equations) are better at USyd. There used to be a BSc(Hons) in maths...

    Questions about mark

    There aren't any "you need to pass the final" rules in math1131. But from what I understand, the way that they get your final reported grade from your raw marks involves a certain amount of moderating the marks. As one lecturer said, "if you do well enough to just pass we give you 50, not if you...

    High Performance Student Plan

    Doing Eng or CS with maths is pretty standard. In practice there wouldn't be much difference between what you did in a BSc (Maths) and the Adv Maths program. (You can do honours at the end of either if your marks are OK). I think I heard someone talking about a new BEng/ Adv Maths double degree...

    High Performance Student Plan

    Every degree has a whole pile of requirements such as compuslory courses, at least so many units of credit of 3rd year,.... Some degrees give you very little choice about what to do. For the maths plans the main requirement is a list of core 1st and 2nd year maths courses which you'd want to do...

    High Performance Student Plan

    The plan is there for a small number of really good students who might otherwise keeping ketting caught up in annoying degree rules because they are trying to do a degree that more advanced the standard one. The school of maths seems pretty good at letting people do things in funny orders if...

    MATH1081 Help

    This is just like writing sum(k^2,k=1..N-1) = 1 + 2^2 + ... + (N-2)^2 + (N-1)^2 = 1 +4+ (N-1)^2 + sum(k^2,k=3..N-2) As TS said, when you put all the sums to be over the same k's so you can combine them, you get several terms left over.
