But, if not — if xy/(x+y)^2≤0, for integer x and y, is the object of direct interest — a related plot can be brought up in the Advanced Graphing app.

Yes, the Advanced Graphing app (which I think is the best thing about anything relating to the Prime) provides a great way to study these kind of inequations. Algebraically though, the Prime CAS is unable to provide any context or clue in about the inequation behavior, while other simpler CAS such as the TI89's can.
