y^{''}-2y^'+y=3cos(2x)

y^{^{''}} - 2 y^{^{'}} + y = 3 cos (2 x)

y = c_{1} e^{x} + c_{2} x e^{x} - \frac{12}{25} sin (2 x) - \frac{9}{25} cos (2 x)

Solution steps

y^{''} (x) - 2 y^{'} (x) + y = 3 cos (2 x)

Solve linear ODE:

y = c_{1} e^{x} + c_{2} x e^{x} - \frac{12}{25} sin (2 x) - \frac{9}{25} cos (2 x)

y = c_{1} e^{x} + c_{2} x e^{x} - \frac{12}{25} sin (2 x) - \frac{9}{25} cos (2 x)
