         26.2.  Solve  x + 2x-8x = e'; x(0) = 1,  i(0) = -4.
                  From  Problem  17.1, this initial-value problem  is equivalent to Eq. (26.1)  with






               and t 0 = 0. The solution is given by either Eq. (26.2) or (26.3). Here, we use (26.2); the solution using (26.3) is found
                                    A(
               in Problem  26.3.  For this A, e  has already  been  calculated  in Problem  16.2.  Therefore,

         26.3.  Use Eq.  (26.3) to solve the initial-value  problem  of problem  26.2.
