#4 Suppose A is a constant matrix with Re(o(A)) 0 and a 0. Let C be a continuous matrix valued function such that for positive constant B we have B ||C(t)|| 0. K Show that the zero solution of z' (t) = [A + C(t)](t), a) stable if B = -a, b) unstable if B > -a, c) globally asymptotically stable if 0 0 and a 0.
