Sample HSC Ext2 Maths Exam: Q16

Q16 from the sample NESA HSC Mathematics Extension 2 exam.

My general thoughts about this question:
(1) RELATIVELY, it is quite approachable compared to other last questions from HSC/trial exams
(2) Q16c ends by finding a value for a (famous) infinite series, which has popped up often enough in the past.... e.g. 2005 HSC q6 had the series for 'e', 2010 HSC q8 had the series for π^2/6 etc.
(3) Q16ciii - Limits often pop up in the harder questions. Be aware of the SQUEEZE THEOREM.

Like Q15, this video was slightly rushed in order to get it uploaded before the 2020 HSC (tomorrow) so if there are any mistakes, please point them out. Also, apologies for all the bird chirping in the background. They were crazy today!

All the best for those doing their exam tomorrow!

How hard would you rate this exam compared to previous years, and would this type of difficulty be common for later years?
