I thought essays were way harder... I found SA unconventional but not too bad really.

Do you guys think the band 6 cut off will be lower than last year (85%)?

Your HSC mark is the average of your assessment mark and your exam mark. Your exam mark is how well YOU do in the exam. Because you are ranked 1st, your assessment mark will be equal to the highest exam mark in your cohort.

In this question, when it says 'let M be the maximum value of |a_n-1|, |a_n-2| ...' EDIT: is it saying M is equal in magnitude to the highest coefficient?

Re: HSC 2015 4U Marathon I would have thought that unless they asked you to use calculus or it had 'hence' in the question (and a previous part involved using calculus) that you would get full marks...

I used a previous part of the question. -1 < x < 1

For this proof, can I do what I did from lines 3 to 4? \sum_{n=0}^{\infty }\frac{x^{2^{n}}}{1-x^{2^{n+1}}}\\=\lim_{N\rightarrow \infty }\frac{1-x^{2^{N+1}}-1+x}{(1-x)(1-x^{2^{N+1}})}\\=\lim_{N\rightarrow \infty }\frac{x(1-x^{2^{N+1}-1})}{(1-x)(1-x^{2^{N+1}})}\\=\frac{x(1-x^\infty...

How did your trials go?
