I'd like to know how I can extract the parameter
values used by ParametricPlot in plotting a curve,
e.g. if ParametricPlot used points corresponding to
parameter values 2, 4, 6, etc... I need a way to get
the list {2, 4, 6, ...}.
One solution I know is this:
list={};
ParametricPlot[(AppendTo[list,t]; {f[t]
g[t]}),{t,tmin,tmax}];
The problem with this is that I get an error that
ParametricPlot cannot compile the function, and that
the plotting time is considerably slowed down.
especially if I have a high PlotPoints setting.
Any ideas?
