y^{''}+9y=2cos(3t)

Solución

y^{^{''}} + 9 y = 2 cos (3 t)

y = c_{1} cos (3 t) + c_{2} sin (3 t) + \frac{t sin ( 3 t )}{3}

Pasos de solución

y^{''} (t) + 9 y = 2 cos (3 t)

Solve linear ODE:

y = c_{1} cos (3 t) + c_{2} sin (3 t) + \frac{t sin ( 3 t )}{3}

y = c_{1} cos (3 t) + c_{2} sin (3 t) + \frac{t sin ( 3 t )}{3}
