This demo displays the several example functions of convex curves. A convex curve is a closed curve, where any two points in the interior of the curve may be connected by a straight line which does not leave the interior of the curve. To change which funtion is viewed, type the function title into the definition of X(t). For example, X(t)=ellipse(t).
Change the value of t0 and other variables as in earlier demos.
As in earlier demos, there are "Show entire curve" and "Show Color Spectrum" options.
