a. Find a particular solution to the nonhomogeneous differential equation y'' + 9y = cos(3x) + sin(3x). y_p = (xsin3x)/6 -[(xcos3x)/6] b. Find the most general solution to the associated homogeneous differential equation. Use c1 and c2 in your answer to denote arbitrary constants. Enter c1 as c1 and c2 as c2. y_h = c1*cos3x + c2*sin3x c.
