Is there a way to put a formula in a variable (as in like a programming language variable) so that it can be referred to and rendered later? I was able to do this in Mathematica, but I'm moving away from Mathematica because I don't want to pay for it. I want to change to something more openly available like LaTex for displaying math formulas.
Note: I'm using Jupyter Notebook, which happens to use MathJax for LaTex rendering.
Though I mentioned programming language variables, Mathematica, and Jupyter Notebook, I am asking about doing this purely in LaTex (MathJax in my case).
I didn't have a lot of time with Mathematica, but here's an example of something that could be done in Mathematica
some_function = a/b x = some_function/c Display[x];
The result would be something like this:
\newcommand, which could go in the right direction.
\pgfmathdeclarfunctioncould also be an option for you.
