Some of the later questions in the Extension paper allow for some cross-fertilisation between topics.  This question links some of the basics from complex numbers and polynomials.

2010 Extension 2 HSC - Ordinary Differential Equations

It appears that over the last few years, there is a trend towards ordinary differential equations (ode's) in the Extension 2 HSC.  They could probably be considered as an extension on the two and three unit problems involving growth and decay.

Here is the 2010 HSC, Question 5
