A question

[TheTwisted1]

Does anyone here know a way to put mathematical formulae, such as those generated by TeX or similar, into LiveJournal posts?
Sorry about this, but I'm not sure who else to ask (there's been no response to my inquiry on this topic in LiveJournal's support area).

given that lj supports HTML, I would imagine you would use tag..

The problem with that is converting the formulas to HTML (or particularly, LiveJournal's restricted subset of it), even preformatted, when the math contains such things as double and triple integrals, path integrals, subsets, complicated exponents, nested fractions, multiple entities or fractions under square roots, matricies, vectors, operators, etc. The preformatting tag does little to help.

almost looks like you'd be best off outputting from TeX into png or gif!Wire Geek - Burning the weak and trampling the dead since 1979Wire Geek - Burning the weak and trampling the dead since 1979

That is generally how most sites get away with it(e.g. Wolfram Research's Math World). Since most fourms/blogs/etc. have little in the way of formatting, and word processing, your best bet is to make a .gif or .png image of your formula(e) and then use the img tag to insert it. for HTML, [] for BBCode, I believe.

Unicode should in theory have the characters for all of that, but many people are probably missing pieces of the Unicode characters. Also conversion to unicode is not exactly straightforward, and the representation is probably a little more awkward (a / instead of a line with text above and below for division, etc) unless you combine it with html.
if you simply wish to display it in your log an image is the best choice I think, but for other uses a different representation might be worthwhile.

Unicode doesn't help as mathematical formulas are not straight lines of text. Unicode assumes text is only moving in a straight line (that line can be left-to-right, right-to-left or even up-to-down, but it has to be straight). Theoretically there is MathML, but I don't know what support is like outside of Firefox and even then, it isn't fully supported in Firefox.
