y^{''}+81y=cos(6t)

Lösung

y^{^{''}} + 81 y = cos (6 t)

y = c_{1} cos (9 t) + c_{2} sin (9 t) + \frac{1}{45} cos (6 t)

Schritte zur Lösung

y^{''} (t) + 81 y = cos (6 t)

Solve linear ODE:

y = c_{1} cos (9 t) + c_{2} sin (9 t) + \frac{1}{45} cos (6 t)

y = c_{1} cos (9 t) + c_{2} sin (9 t) + \frac{1}{45} cos (6 t)
