Webin (6) is satisfied. Substituting t0 into (5) gives us the matrix equation for c : X(t0)c = x0. Since the determinant X(t0) is the value at t0 of the Wronskian of x1 amd x2, it is non-zero since the two solutions are linearly independent (Theorem 5.2C). Therefore the inverse matrix exists (by LS.1), and the matrix equation above can be ...
