By using the method of power series, solve the initial value problem given by: (x"+1)y" + xy' + 2y = 0 y(0) = 0 ; y'(0) = 1. at the ordinary point x_0 = 0. Solve the following system y' + 2x' - 3y = -e^t sint x' - 4y + x = e^t cost. a) Verify that y_1 = x + 1 is a particular solution of (E) : xy" - 2(x + 1)y' + 2y = 0 b) By using the reduction order method, find the general solutions of (E).
