Objet?: [Maxima] (a-b)^odd+ (b-a)^odd --/--> 0
Maxima is unable to simplify (a-b)^n + (b-a)^n to zero, where n is a large
odd integer:
(%i7) e : (a-b)^10001 + (b-a)^10001;
(%o7) (b-a)^10001+(a-b)^10001
(%i8) rat(e);
Maxima encountered a Lisp error: < junk deleted>
ratsimp and radcan have the same problem. With about 22 calls to 'go', the
simpexpt code isn't too
much fun (at least for me) to look at, extend, or fix. I don't think the
(a-b)^n + (b-a)^n
simplification problem is all that worrisome.
