van der Pol Equation
An Ordinary Differential Equation which can be derived from the Rayleigh Differential Equation bydifferentiating and setting 
. It is an equation describing self-sustaining oscillations in which energy is fed intosmall oscillations and removed from large oscillations. This equation arises in the study of circuits containing vacuumtubes and is given by
