Hey all,

We apologise for the delay, but the solutions, marking criteria and markers comments are finally here!

Please note that these solutions are still somewhat in draft mode so if you see any errors, please feel free to PM either myself or Trebla.

We hope that these will be of some use to you (or to future students reading this message).

Good luck all for your HSC, and I'll see you all again for my HSC solutions on Wednesday =)

Carrot.

Cheers! Trebla will get on to that when he returns from work, as I don't have access to the TeX file =(

In my booklet, Option D in Question 9 was printed as |x|≥tan^-1x which is true, not |x|>tan^-1x (difference being it has a greater than or equals sign, and thus the equality at x=0 doesn't make it false).
