Apologies, was on phone :)

Yup, I am only interviewing for the Finance & banking scholarship. Mine is on 26th Nov, 9:30 am Wbu?

Thanks for the response, If you don't mind me asking, which course are you undertaking for your coop?

Hi everyone, This is just a general post on the UNSW Co-op Scholarship interviews (specifically, Finance & Banking): Could any current co-op scholars or any successful candidates who have been eligible for an interview, shed some light on what the interview will be like (as detailed as...

Will be going and bringing friends :D

Re: HSC 2013 4U Marathon Hey guys, a short question. Pretty simple but i really liked it :) $ If $ \alpha , \beta $ are two complex numbers where $ \alpha\neq\beta $ and $ |\alpha|=1, $ show that $ \left |\frac {\alpha\bar{\beta}-1}{\alpha-\beta} \right |=1

I think it was one of those promotion pens? :) Just a normal ball-point pen i think, Why?

What they said but here's a diagram which may ALSO help you understand it a bit better :) NOTE: This solution is "diagram dependent", so it only proves one case. However it will work wherever you draw Z1 and Z2, yielding a result of either pi/2 or -pi/2, which means it is always purely imaginary.

Yh, Sorry just saw you're message about the Dot Points books, which ones did you have? Could you link me to the thread?

Kirchoff's Law of Voltage Drop :)

Hey, does it have any writing in it? How's the condition, etc.? Can you go down a bit further still, it's still a bit pricy >< a lot of people are selling on BOS for 10 or 15 and i'm buying 2 at once ahaha :)

\\ $ 5. (I THINK this question is done similarly to question 4.) \\\\ $ V = \int ^{h}_{0} A(x)dx \\\\ \begin{align*} A &\approx \frac{h}{3}[y_{0} + y_{4} + 2y_{2} + 4(y_{1} + y_{3})] \\ &= \frac{20}{3}[64 + 88 + 2(146) + 4(98 + 160)] \\ &= 9840 m^2 \end{align*} \\\\ $ Therefore $ V = 9840 m^3

\\ \pi r^2 h = 16 \pi \Rightarrow r^2 = \frac{16}{h} \\\\ SA=2 \pi r^2 + 2 \pi r h = \frac{32 \pi}{h} + 8 \pi \sqrt{h} \\\\ \frac{d}{dh} SA = - \frac{32 \pi}{h^2} +\frac{4 \pi}{\sqrt{h}} = 0 $ for max/min$. \\\\ \frac{4 \pi}{\sqrt{h}} - \frac{32 \pi}{h^2} = 0 \\\\ 4 \pi h^2 - 32 \pi \sqrt{h} = 0...
