I’ve just added LatexRender support to this weblog, using Steve Mayer’s WordPress plugin. In principle you should now be able to add formulas in TeX in the comments by putting the TeX in between [tex ] and [/tex ] (without the space).
Here’s an example of the output:
I fear this will undoubtedly require some further debugging, but no time for that right now.
Update: This is now long out of date. I’ve replaced LatexRender with MathJax support. The opening and closing delimiters for tex math are now ‘\$’ and for displayed math are “\$\$”.
