(d^2x)/(dt^2)+4x=cos(3t)

Lösung

\frac{d ^{2} x}{d t ^{2}} + 4 x = cos (3 t)

x = c_{1} cos (2 t) + c_{2} sin (2 t) - \frac{1}{5} cos (3 t)

Schritte zur Lösung

\frac{d ^{2} x}{d t ^{2}} + 4 x = cos (3 t)

Solve linear ODE:

x = c_{1} cos (2 t) + c_{2} sin (2 t) - \frac{1}{5} cos (3 t)

x = c_{1} cos (2 t) + c_{2} sin (2 t) - \frac{1}{5} cos (3 t)

x \to 2 lim (4 - a \cdot x)
