Mar17 comment Writing mathematical presentations using mathjax MathJax can't determine the sizes of element in a container that is display:none so you need to use some other techniques to achieve the same result. See the examples in the slides from my talk at the Joint Math Meetings in januarty Feb1 revised Non linear phase portrait Corrected math formatting Feb1 suggested approved edit on Non linear phase portrait Aug29 comment Show that $A\Delta B = C$ if and only if $A = B\Delta C$ @Harold, if you have the STIX fonts installed, that might be the culprit, as the big triangle in that font is a bit larger than TeX's version. There is not a lot of choice in the triangles within a font, I'm afraid. Jul10 revised Check if $(\mathbb Z_7, \odot)$ is an abelian group, issue in finding inverse element Replace faked arrows with \xrightarrow and \xleftarrow Jul10 suggested approved edit on Check if $(\mathbb Z_7, \odot)$ is an abelian group, issue in finding inverse element Apr26 comment What is $\limsup\limits_{n\to\infty} \cos (n)$, when $n$ is a natural number? @Fabian, yes, there is a bug with \limsup and \liminf in SVG mode. It will be fixed in the net release of MathJax.
