the pairs (x(t), y(t)), for a<= t <=b, with a point tracing out the curve
and leaving behind a faint image of the path. It would also be very useful to be

with the subject of parametric curves and I think such software could greatly
help them to grasp what's going on.
If there are good examples of such software already in existence, please point
us!
