1. The problem statement, all variables and given/known data Write the given system in the form [tex]x'=P(t)x + f(t)[/tex] [tex]x'=-3y , y'=3x[/tex] 2. Relevant equations [tex]x'=P(t)x + f(t)[/tex] [tex]x(t)=c_1x_1(t)+c_2x_2(t)+...+c_nx_n(t)[/tex] 3. The attempt at a solution I have no idea how to start this since my teacher never covered this in our notes and the book doesn't give an example of this type of problem. Please help!
