This module is a graphical exercise on parametric curves in
the cartesian plane.
A parametric curve is determined by two real functions
and of a parameter . This curve is therefore the set of points
for different values of t. On the other hand,
we also have the graphs of the two coordinate functions and
which are curves.
This exercise can either present the two curves of and
and ask you to recognize the parametric curve
among others, or present the parametric curve and ask you to recognize the
curves of and .
