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 $g$.
