Yes, it is. You write a simple plugin (in Python) that gets called by
sphinx when you write something like:
Some paragraph, bla bla, and some equation:
.. sage:
sin(x).diff(x)
and you do whatever you want.

I see. My goal is to go one step further and have something, so that I
can enter formulas (at least some simpler ones at the beginning) using
sympy (or Sage in your case, that doesn't really matter), and just
keep it in that form, and it would somehow automatically be converted
to latex. And in the html output, I can imagine a link, that would
allow me to modify such formula (using some web interface to sympy /
Sage). Also so that I can only create some calculation and simply tell
it (somehow) that these and those results should endup in the
document, without having to copy & paste or worry about anything.
And of course to autogenerate some tables, as you do too.
