I'd like to create an ellipse (using psellipse, say). Call it E. And I'd like to specify a point P outside E. And then I'd like to construct, using PSTricks, the two rays starting at P and tangent to E.
Is there an easy way to do this?
I know I could do this by doing it for a circle and then "stretching" the picture to make it an ellipse, but that complicates other things I'd like to do. And of course one could figure this all out using explicit computations. But I'd like to know if there is some simple straightforward way.
