Hello!
I wonder if there is any way of plotting parametric curves where the parameter can't be expressed in terms of variables ("x" and "y").
Example 1: Parametric curve x=t^3 - 4t, y=t^2 can be plotted by using this equation x=sqrt(y)*(y-4). File attached.
Example 2: Parmetric curve x=t^2 * sin(t), y=t^2 * cos(t) - "t" can't be expressed easily in terms of "x" and "y".
(or is it correct to write t=asin(x) * (asin(x))^2 ?)
Best,
Sergey
