(d^2-1)y=x^2cos(x)

(d^{2} - 1) y = x^{2} cos (x)

y = c_{1} e^{x} + c_{2} e^{- x} - \frac{x ^{2} cos ( x )}{2} + x sin (x) + \frac{1}{2} cos (x)

Solution steps

(d^{2} - 1) y = x^{2} cos (x)

Solve linear ODE:

y = c_{1} e^{x} + c_{2} e^{- x} - \frac{x ^{2} cos ( x )}{2} + x sin (x) + \frac{1}{2} cos (x)

y = c_{1} e^{x} + c_{2} e^{- x} - \frac{x ^{2} cos ( x )}{2} + x sin (x) + \frac{1}{2} cos (x)
