[New-bugs-announce] [issue21902] Docstring of math.acosh, asinh, and atanh

[Kevin Davies]

New submission from Kevin Davies:

The docstring of acosh should more accurately be 
"Return the area hyperbolic cosine of x."
instead of 
"Return the hyperbolic arc cosine (measured in radians) of x."
asinh and atanh should be changed similarly.  The result of these functions is not an angle but a ratio of areas.  See 
http://en.wikipedia.org/wiki/Inverse_hyperbolic_function.
