A small nice-to-have: it would be good to document the range of the inverse trigonometric functions `math.atan`, `math.asin` and `math.acos`, in both the docstrings and the built documentation.

There are standard "principal values" for each of these inverses, and Python is using these standard values, but that may not be obvious to a user.

I created a small diff to update the documentation of `math.atan`, `math.asin` and `math.acos`.
