### What differential equation might model this almost-harmonic oscillator?

I need to precisely control the motion of a damped, driven (nearly) harmonic oscillator: $$\ddot x(t) + \alpha\dot x(t) + \omega_0^2 x(t) \approx V(t)$$ I use the $\approx$ symbol because this is ...

### Mathematical interpretation of pressure (gradient)

I'm having some problem with the following. Usually, the pressure of some mass on an area A is defined by $$P=\frac{F}{A}$$ where $F$ is the force of the mass exerted due to gravity. However, here ...
