Ya thats for plot, I think we need a slightly different approach for
parametric_plot.
The common demand is that the curve shall lo

In both cases, it's plotting points approximately evenly sp
Another evil example:
parametric_plot((lambda x: arctan(x),lambda x: arctan(x)**2),
(-1000,1000))
It seems that the plot algorithm is somehow deficient in those cases.

I thought plotting are just some arithmetical operations for around
hundret points, why can it slow down so
