1. The problem statement, all variables and given/known data Prove that x(t) = c1y1e^-2t + c2y1e^5t is a solution to x' = Ax given that y1 is the matrix ( 1 ) ( -3 ) and y2 is the matrix (2) (1) 2. Relevant equations 3. The attempt at a solution I've never had to do a lot of proofs and I am not really sure of where to start this problem. I know I'm supposed to differentiate X but I don't know how to do so..
