Damped Pendulum Example
The motion of a damped pendulum (i.e., a pendulum with friction slowing
it) is described by a periodic function (cosine) whose amplitude decreases
as time increases in proportion to a negative exponential function.
The initial trial values for the parameters are specified on the
Parameter statements.
