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

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.

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.

comment Showing there is an exact sequence
I have made some edits to improve the layout of the commutative diagram, but it won't be available until peer reviewed, since I don't have editing privileges.

comment Covering dimension of the union
Your example should be {\rm Int} A rather than \rm{Int} A, since \rm doesn't take a parameter — it is simply a switch that changes the current font.
