Hi Matthias, Aaron, All,
It works. I've hacked something together to add a \label{...} inside the
equation environment. It is called like this:
init_printing(latex_mode="equation", label="quadratic")
display(ex2)
Now the equation can be referenced using \ref{quadratic} or \eqref{quadratic} in
a notebook markdown cell.
init_printing() needs to be called to set the equation reference before every
display() call. Once init_printing() is called with a label argument it will
persist thereafter. This is kind of clunky but it gets the job done.
In PDF output from 'jupyter nbconvert' the numbering works but in interactive
Jupyter views the equation references display as ???, which was expected.
It doesn't work in the vscode Jupyter extension because that uses KaTex, which
doesn't support equation references and produces an error message instead of
displaying the equation.

A question now is if I did that and referred to that in the markdown with
something like this: $\@ref(foo)$, would that get picked up? I'm really only
You should not use $-signs, because references don't happen in math
mode, they are part of normal text.
The correct usage is \ref{foo} or \eqref{foo}, without any additional
characters.
interested in this for static presentation output (pdf, html) so it wouldn't
matter if it doesn't work in interactive modes.
I think the only way to know if it will work or not is to test it. I
suspect it will work for pdf output, but I have no idea if it will
work in the browser. It depends on whether MathJax supports \ref.
MathJax does support \ref{...}, as long as it is configured appropriately.
There are some examples in the nbsphinx docs:

This also works on nbviewer (which is based on nbconvert):
https://nbviewer.org/urls/nbsphinx.readthedocs.io/en/0.9.3/markdown-cells.ipynb#Manual-Equation-Numbering
It also works on Github:
https://github.com/spatialaudio/nbsphinx/blob/0.9.3/doc/markdown-cells.ipynb
Of course, this also works for PDF output:
https://nbsphinx.readthedocs.io/_/downloads/en/0.9.3/pdf/
It does work on the old Jupyter notebook:
https://mybinder.org/v2/gh/spatialaudio/nbsphinx/0.9.3?filepath=doc/markdown-cells.ipynb
And it does work on JupyterLab:
https://mybinder.org/v2/gh/spatialaudio/nbsphinx/0.9.3?labpath=doc/markdown-cells.ipynb
cheers,
Matthias
