Re: HSC 2015 4U Marathon Next Question: $ Suppose that $ a $ and $ b $ are real numbers (not both zero) and $ w=\frac{az+bz^{-1}}{bz+az^{-1}}. $ $ \\ $ Show that if $ |z|=1 $, then $ |w|=1. $ $

Re: HSC 2015 4U Marathon $ Consider the graph of $ P(x) = x(2x+1)^2 $ and observe where the line $ y=-k $ intersects the graph. For $ y>0 $, the line intersects the curve once (hence we exclude this region), for $ y\le0 $, the line then intersects the curve once or twice. To determine where...

Re: HSC 2015 4U Marathon Alternate Solution :) $Since$\ z = a(\cos\theta + i\sin\theta) \Rightarrow |z|=a \Rightarrow |z|^2=a^2 \Rightarrow z\bar{z}=a^2. \\ \therefore \frac{z}{z^2+a^2}=\frac{z}{z^2+z\bar{z}}=\frac{1}{z+\bar{z}}=\frac{1}{2a\cos\theta}

It's ACCT1511 haha. Yep, that plan is fine too :)

Yes, you can still change your timetable, SWAP means that you want to change you lecture/tutorial times whilst still being enrolled in the course, whereas DROP is used to disenroll from a course completely and change to another course if you wish.

Well yes, all the MATH1XX1 courses as listed in the handbook are taken by students in their 1st year, but MATH1081 can be done in later years if you wish, although I would recommend for you do it first year :) NOTE that MATH1081 is only a recommended course, so you if find that you do not want...

To do a major in Maths or Stats, you would need to do the following (first-year) courses: Stage 1 MATH1131 or MATH1141 Mathematics 1A (SEM1) MATH1231 or MATH1241 Mathematics 1B (SEM2) MATH1081 Discrete Mathematics (Highly Recommended) (can be done in SEM1 or SEM2)

Do it in either your 2nd/3rd/4th year, it is a really bad course and very irrelevant to any other course in the degree so it is not a problem if you leave it till too late.

Yep, your enrolment is fine for SEM1, in SEM2 most people usually pick ACTL1101, ACCT1511, ECON1102 & MATH1251. Don't worry about it for now, you will enrol for SEM2 courses sometime around May so you will plenty of time to plan out your SEM2 timetable.

Refer to the following link: http://www.handbook.unsw.edu.au/undergraduate/programs/2015/3435.html Enrol into the compulsory courses you are meant to for Stage I and see if there are any other courses you would like to pick corresponding to your major.

Re: UNSW Chit Chat Thread 2015. May

These are the courses you should enrol in: - MATH1151 - ACCT1501 - ECON1101 - FINS1613 or MGMT1001 (doesn't really matter although many tend to do FINS1613 as it is more relevant towards your other courses and helps for ACTL1101 in SEM2) NOTE: Do FINS1613 in SEM1 only, even if you decide not...

Re: UNSW Chit Chat Thread 2015. You should be fine, there are usually plenty of tutorials that are allocated at pretty good times so you won't really be stuck with early morning or late night tutorials if that's not what you want. The earlier you enrol, the better it will be as you will have...

Re: UNSW Chit Chat Thread 2015. First semester only, SEM2 courses you will pick towards the end of SEM1, sometime in mid-May.

Re: UNSW Chit Chat Thread 2015. 41/51 in both semesters are actually very similar in content but the order of topics slightly changed around i.e. MATH1151 kids learn Probability/Statistics in SEM1 whilst MATH1241 kids will learn it in SEM2. However, in MATH1251 they do introduce more topics...

Hmm, this is strange because when I enrolled in it in late Feb last year, there were way more free classes and I still ended up getting a good timeslot (same with a lot of other first year ACTL kids). I don't know if they will open more classes for it soon or if that there are A LOT of 2nd/3rd...

I guess it doesn't really matter since everyone has to do it at some stage, but since the course is of huge inconvenience most people tend to do the more important/common courses earlier and leave MGMT for later years since finance in general plays its part in ACTL courses. Also, since you are...

FINS1613 is better in SEM1 for the following reasons: - Very good and engaging lecturer who loves to give extra marks for most quizzes, homework and the final exam - Course is all MC and all the class quizzes are pretty straightforward so easy marks there - If you can add, subtract, multiply...

Do FINS1613 in SEM1 and delay MGMT1001 to your 4th year as it is a notoriously bad course. Do your MATH1081 in 2nd or 3rd year, depending on what you want to major in, as different majors may require slightly different courses for 2nd year (although most of them are the same) and that the 2nd...
