I was wondering whether it would be difficult to get the physicsforums engine to recognise a delimiter for in-line math that is also recognised by most LaTeX engines, such as $or $$. Alternatively, has anybody written a plugin or script that converts standard latex to physicforums latex? It would need to first convert all double- to something else like %%, then convert all single- symbols to double-#, then convert all %% back to double-. Ideally there would be a reverse converter too, so that if one wants to do major surgery on a maths piece on physicsforums, they could convert it to standard latex, do the surgery offline then convert it back. thanks Andrew 2.

However, it seems to me that \( and$$ would be a reasonable alternative. In fact the MathJax documentation uses them as an example in the section on configuring the tex2jax processor: https://docs.mathjax.org/en/v2.5-latest/options/tex2jax.html @Greg Bernhardt is the one who's responsible for this stuff, so let's see what he says. 3.

Quote my post to see the source code.

Alternatively, use $formula$ and $$formula$$

It will show the source code if there is a parsing error, usually from unrecognized control sequences or mismatched brackets.
