Re: HSC 2013 4U Marathon Here's my go at the question. I'll just do the left inequality and presume the right inequality is similar. \frac{x^{n+1}-y^{n+1}}{x-y}=x^n+x^{n+1}y+...+xy^{n-1}+y^n =y^n(1+\frac{x}{y}+\frac{x^2}{y^2}+...+\frac{x^n}{y^n})>y^n(n+1) As \left ( \frac{x}{y} \right )^k>1

I'm looking at Discrete Maths 1081 and I was wondering whether or not I have to go to all the lectures.

Yeah I did and I'm looking at the handbook. But it doesn't tell me what courses I need to do.

Can someone tell me what the core components/courses of Commerce/Adv maths is at UNSW. I can't find then anywhere.

I'll put up a question for now: Show, by mathematical induction, that |z_1+z_2+⋯+z_n |≤|z_1 |+|z_2 |+⋯+|z_n |

Sorry to hijack this thread OP. But what do you think are my chances of commerce at unsw if my atar (with bonus points) adds up to 99.95?

Re: FAQ: Late Round Offers What are the chances of getting an offer in normal commerce in Usyd/UNSW?
