Damped harmonic oscillator equation¶
Describes the motion of a single-degree-of-freedom mechanical oscillator that experiences linear (viscous) damping.
Conditions:
Damping force is directly proportional to velocity (viscous).
Motion is restricted to one spatial dimension.

- definition¶
Derivative(x(t), (t, 2)) + 2 * zeta * w * Derivative(x(t), t) + w^2 * x(t) = 0- Latex:
- \[\frac{d^{2}}{d t^{2}} x{\left(t \right)} + 2 \zeta \omega \frac{d}{d t} x{\left(t \right)} + \omega^{2} x{\left(t \right)} = 0\]
