y^{''}+36y=-60sin(6t)

Lösung

y^{^{''}} + 36 y = - 60 sin (6 t)

y = c_{1} cos (6 t) + c_{2} sin (6 t) + 5 t cos (6 t)

Schritte zur Lösung

y^{''} (t) + 36 y = - 60 sin (6 t)

Solve linear ODE:

y = c_{1} cos (6 t) + c_{2} sin (6 t) + 5 t cos (6 t)

y = c_{1} cos (6 t) + c_{2} sin (6 t) + 5 t cos (6 t)

\frac{d y}{d t} = - 2 (1 + y^{2}) tan (2 t)
