Ah, I see. If there was were primitive functions for LessThan(x,y), Equal(x,y), and GreaterThan(x,y), and they returned 0 or 1, I think that's all I would need: f(x,y) = y + LessThan(x,pi/2)*f1(x) + Equal(x,pi/2)*f2(x) + GreaterThan (x,pi/2)*f2(x) I don't suppose these exist or are easy to define? Thanks again for the super-quick replies!
