This module is a graphical exercise on parametric curves in the cartesian plane.

A parametric curve is determined by two real functions *f*
and *g* of a parameter *t*. This curve is therefore the set of points
(*x*=*f*(*t*),*y*=*g*(*t*)) for different values of t. On the other hand,
we also have the graphs of the two coordinate functions *f* and
*g* which are curves.

This exercise can either present the two curves of *f* and
*g* and ask you to recognize the parametric curve (*x*=*f*(*t*),*y*=*g*(*t*))
among others, or present the parametric curve and ask you to recognize the
curves of *f* and *g*.
