Hi everyone,
I am running Sage v 9.6.beta4 on Ubuntu 20.04 LTS system. When I run
doctests on it, it skips the doctests involving pytest, saying that
```
Pytest is not installed, skip checking tests that rely on it.
```

Actually a dependency of jupyterlab_widgets to ipympl has been introduced
in Sage 9.6.beta5, so that as soon as you
I think I am going to have a "moment" here! Thanks!
This sheet is just great; all the things I have wanted to do,
demonstrated :)
I do have some trivial suggestions (to make it even more impressive)
1) I had to do
pip install ipympl
Would it be reasonable to do a try/except in the header?

atanh, etc., i.e. just "a-"-prefix is well in line with the tradition of
Fortran libraries,
as well as C libm's.
It's "arctanh" in the NIST Digital Library of Mathematica
Mathematica, Maple, and numpy all use "arctanh"; MATLAB uses "atanh". It's
"arctanh" in the NIST Digital Library of Mathematical Functions as well:

It is the case that "ar-" prefix is the current ISO standard, and per the

Dear sage developers,
Let me advertise the nice notebook for testing display in Jupyter,

Great. Thank you. That worked.

I'd be in favor of the change (keeping arc- as an alias, of course). It is
not a good experience to explain in the course how the function is defined,
and then see sage print it wrong.

Sorry for a tangential question - the overview page seems to imply that
*everything* from a (current) Jupyter notebook will work in a Jupyterlab
instance (and, by extension, presumably can easily be imported). Would
that include the widgets we use for @interact?
(Tail wagging the dog here is t
In terms of the missions statement, apparently we aren't the only ones, so
consistency might be more important in any
case: https://reference.wolfram.com/language/ref/ArcTanh.html
Note e.g. sympy uses atanh as the
"ordinary":

You can download the pythran 0.11.0 source tarball from
https://pypi.io/packages/source/p/pythran/pythran-0.11.0.tar.gz
(as found in `build/pkgs/pythran/checksums.ini`)
and place it in the `upstream` folder of your Sage installation.
Alternatively, you can use
```
./configure --enable-downloa
Note that Sage also provides aliases with `a-`
(the display is still with `arc-`):
```
sage: asinh, acosh, atanh, acoth, asech, acsch
(arcsinh, arccosh, arctanh, arccoth, arcsech, arccsch)
```
