Please Help!

4. (15 points) Using either Undertermined Coefficient or Variation of Parameters method solve the following differential equations (a) y(2) - 2y (1) + 2y = (cos(x) - 3 sin(x))e2x (b) i - wax = Fosin(wt) s.t. x(0) =0, x(1)(0) =0 (c) y(2) + 4y = g(x) s.t. y(0) = 1, y(1)(0) = 2 sin(x) OKx 71 /2
