Comment (by kcrisman):
> The following functions are not fixed: `atan, acos, asin` because I am
not very sure how they get evaluated. I have fixed the other functions to
take `complex` type as input.
You'll notice that
[http://git.sagemath.org/sage.git/tree/src/sage/functions/trig.py#n562
here]
{{{
arctan = atan = Function_arctan()
}}}
so `atan` is exactly the same as `arctan` - one fix works for both!
