Jupyter doesn't use the built-in MathJax
I open up the jupyter notebook:
sage -n jupyter. I open a notebook and what I get is
Math/LaTeX rendering will be disabled.
If you have administrative access to the notebook server and a working internet connection, you can install a local copy of MathJax for offline use with the following command on the server at a Python or Jupyter prompt:
from Jupyter.external import mathjax; mathjax.install_mathjax()
But I don't want a third (sic!) copy of MathJax on my computer! How can I make Jupyter use the existing ones?
I'm using Linux Mint 17.2, used the sagemath-upstream-binary package from the PPA.
