1. The problem statement, all variables and given/known data Find the solution of the initial value problem. x'=[3 9; -1 -3]x, x(0)=(2 4)T 2. Relevant equations A good guess should be x=tert$ + ert# 3. The attempt at a solution But .......... the only root is r=0, which gives me a solution x(1)(t)= C1(-3 1)T. Using the guess above, stuff goes wrong because I end up with tA$ + A# -$ = 0, which just gives me #=(-3 1)T as well.
