Differential Eqns. F22-22 -- Matrix exponentials and method of undetermined coefficients

The one where we talk about how to compute matrix exponentials quickly and easily for matrices where all eigenvalues are the same. We also start talking about nonhomogeneous systems and do some simple method of undetermined coefficients (really undetermined vectors).
