    Find the particalur equation for the given initial conditions

    The answer I got was y(x) = e-x(5cosx +5sinx) Is that correct?

    Find the particalur equation for the given initial conditions

    Find the particleur equation for the given initial conditions:- 1/2y'' + y' + 13y = 0 ; y(0) = 5, y'(0) = 0 The only method I know how to solve these doesn't seem to work. Any help is much appreciated.
