Can someone please explain this to me: (M v4.something) In:= Simplify[ArcTan[-x]+ArcTan[x]] Out= 0 In:= Simplify[ArcTan[-x,1]+ArcTan[x,1]] Out= ArcTan[-x,1]+ArcTan[x,1] Note, I want something more complicated than this obviously. Actually want something like Simplify[ArcTan[-x,y]+ArcTan[x,y]] but above is the easiest example of this infuriating programs problem. Cheers, Mathieu
