title: Plotting Cartesian Product of two infinite sets
body: <p>The problem regarding plotting of Cartesian product of two finite sets have been dealt with previously in this forum.
  My concern is that I have two infinite sets and I want to plot the cartesian product of that.
  For example :<code>$X = {t \in \mathbb{R} | (2cos(t) , 3sin(t))}$ and  $Y = {x | 0 \leq x \leq 1}$</code>
  and I want to plot X x Y.
  What is the way to do it ?
  I am using MATLAB for the plots. But I have access to python , Scilab and R too.</p>
