Answers to question 1(c) Sheet 2 and 3(a,b) Sheet 1
Someone alerted me to the fact that there is a mistake in this answer. The method is in principle ok, but after the change of coordinates that leads to the decoupling of the ODE it is claimed that a simple ODE for z has a certain simple solution. In this solution the variables a and b appear slightly wrongly: the first two terms should be -bt/a-b/a^2 (so a and b should be interchanged). This has now been corrected.
There is also a typo in the answer of questions 3(a,b) of sheet 1. The answers are correct but in both parts we have A=PJP^{-1}. This has now been corrected.

Think there's a mistake with the solutions to PS1 Qu.3 parts a and b.
You've written A = (P^-1)JP but it should be A = PJ(P^-1).
Your answers are correct I think it's just you've written it the other way around.
Maybe I'm doing something wrong but it seems wrong to me.
Kind regards
Michael
