here's a test:(adsbygoogle = window.adsbygoogle || []).push({});

[tex] \mbox{erf}(x) \equiv \frac{2}{\sqrt{\pi}}\int_0^x e^{-t^2} dt [/tex]

if this shows up in the "red letter edition", i hope the good folks making this forum happen can take notice.

if the LaTeX math shows up okay, then the problem is very, very weird because a post of mine simply in the Classical Physics forum will not display the TeX.
