van der Pol Equation
The van der Pol equation is an ordinary differential equation that can be derived from the Rayleigh differential equationby differentiating and setting 
. It is an equation describing self-sustaining oscillations in which energy is fed into small oscillations and removed from large oscillations. This equation arises in the study of circuits containing vacuum tubes and is given by
If 
, the equation reduces to the equation of simple harmonic motion
