As part of a check to see if a function can be separated into a product of functions of its individual variables, I'm trying to implement an algorithm based on a theorem by Jose Angel Cid ( http://webs.uvigo.es/angelcid/Archivos/Papers/IJMEST.pdf)
I need to select a point of (x,y) such that f(x,y) != 0. How should I go about implementing this? Should I randomly keep trying values and checking if they evaluate to zero using expr.subs() or should I first evaluate the expression using solve(), and then choose points from RR that don't fall in the solution set of f? i.e. if f(x,y) = 0 for x,y = (1,2), then I would choose a random point from RR - (1,2) In my opinion, the second approach seems more logical.
