Status: New Owner: ---- Labels: Type-Defect Priority-Medium New issue 1676 by b.berret: simplification of type sin x.cos y + cos x.sin y = sin (x + y) does't work http://code.google.com/p/sympy/issues/detail?id=1676
Hi everybody, Simplifying the following trigonometric formula does not work for me. For instance, the commands: trigsimp(sin(x)*cos(y)+cos(x)*sin(y)) or trigsimp(sin(x)*cos(y)+cos(x)*sin(y),deep=True,recursive=True) do not yield the expected result that is to say sin(x+y) For instance, this works perfectly in Maple with the combine(...,trig) command (not tested with others, but I guess it also work, since it is a standard trig simplification).
