[issue21902] Docstring of math.acosh, asinh, and atanh
Kevin Davies added the comment: I'm not sure what the resolution is (the patch was 'inverse', Mark said he'd be happy to use 'area', and Raymond quoted 'arc'). I didn't know this would be a big deal, and I'm sorry that I caused trouble. But since one of the concerns was divergence, I thought I'd send some info on how the tools I've used describe it -- universally as 'inverse' in those that I found: - Mathematica: ArcCosh[z] gives the inverse hyperbolic cosine [...] (http://reference.wolfram.com/mathematica/ref/ArcCosh.html) - Modelica Standard Library: acosh Inverse of cosh (area hyperbolic cosine) (http://reference.wolfram.com/system-modeler/libraries/Modelica/Modelica_Math_acosh.html) - Maple: arccosh, but unknown description (http://www.maplesoft.com/support/help/Maple/view.aspx?path=invtrig) - MATLAB: acosh Inverse hyperbolic cosine (http://www.mathworks.com/help/matlab/ref/acosh.html) - TI-89 calculator: cosh-1 returns the inverse hyperbolic cosine [...] (from manual) Respectfully, Kevin -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21902 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Kevin Davies added the comment: Unfortunately I'm not currently set up with Mercurial and I'm not sure that it makes sense to get that going just for this.

Kevin Davies added the comment: Yes, 'inverse' is probably more obvious to understand than 'area', although it doesn't tie into the 'a' of 'acosh', etc. On 07/01/2014 08:24 PM, Mark Dickinson wrote: Mark Dickinson added the comment: How about simply 'inverse hyperbolic cosine', etc. I think that's more likely to be immediately obvious to readers. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21902 ___ -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21902 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue21902] Docstring of math.acosh, asinh, and atanh
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.
