This represents the system associated with the 2nd
order, nonlinear, homogeneous ODE with constant coefficients that
describes the motion of a damped pendulum.

The ** linearization** of this system is accomplished via the four
partial derivatives

evaluated at any critical point

Once the linearization has been formed, we use ` cclin.m` with

to investigate ** stability** about each .
The ` symbolicplot` option ` `eigenvals'` is useful only for
the linearization.
