I wrote a routine the other day to display the points that Plot actually
uses. Much to my surprise, when I set PlotPoints to some number like 5,
I found that more than this number were actually used.
For example, try this
p1 = Plot[x^2, {x, 0, 2}, PlotPoints ->5, PlotRange ->All];
and then to
p1//FullForm
You will see that 19 points are actually used. Given all that, what does
the PlotPoints option really do?
