y^{''}+25y=-20sin(5t)

Lösung

y^{^{''}} + 25 y = - 20 sin (5 t)

y = c_{1} cos (5 t) + c_{2} sin (5 t) + 2 t cos (5 t)

Schritte zur Lösung

y^{''} (t) + 25 y = - 20 sin (5 t)

Solve linear ODE:

y = c_{1} cos (5 t) + c_{2} sin (5 t) + 2 t cos (5 t)

y = c_{1} cos (5 t) + c_{2} sin (5 t) + 2 t cos (5 t)
