Hello,
while using Mathematica 4.0.2.0 to plot a Lissajous-figure with
ParametricPlot[{Cos[500t], Cos[500t + Pi/4]}, {t, 0, 2Pi}]
I found that with growing coefficients of t the figure (which should
be a ellipse with an angle of 45 degrees between its longer main axis and
the x axis) have the effect of filling up the whole ellipse with
points. Is this an effect of rounding errors or is this a bug in
mathematica?
