Thus 0 0 e3t 894 The exponential matrix is eAt S eJt S-1 e2t - 1 t e2t e3t e2t e3t eAt 0 e2t 0 0 e2t e3t e3t The general solution of the homogeneous differential equation is _ A t x eAt c. 2. The solution of the inhomogeneous differential equation subject to the initial condition is x eAt 0 eAt i e Ar g T dT Jo x eAt r A g T dT o Solution 1. dx dt t x a b c d I The first component of this equation is tx 1 ax1 bx2. .
