Does Math like $f (x) = e^{- x}$ work on askbot?

edit

This is a test. Consider a curve $E$ defined by $y^2 = x^3 + ax + b$. Also consider the Fermat curve $x^n + y^n = z^n$.

(Just testing -- pay no attention to the man behind the curtain.)

${{G}_{-}}\cong {{N}_{-}}\times (U(n-1)\times {{\mathbb{R}}^{+}})$. Note the analogy with the Euclidean similarity group $\text{Sim}({{\mathbb{R}}^{2n+1}})={{\mathbb{R}}^{2n+1}}\times (\mathrm{O}(2n+1)\times {{\mathbb{R}}^{+}})$.

I created a patch for the markdown2.py module that does a better job of isolating MathJax equations from the Markdown processing. Basically, it just replaces all instances of $...$ and $$...$$ patterns from the text, performs the standard markdown processing, and inserts them back in. It works surprisingly well. You can download the context diff from this link (this is just a text file).

The only downside that I can see is that you need to backslash all regular dollar signs that you use in text---but if you run a math-heavy web site like I do, that's no big deal.

Anyway, the Javascript module needs a similar update so that the functionality matches. I've worked on that already, and once I'm satisfied I'll share it here, too. EDIT: OK, I'm satisfied with that patch; you can grab it from this link.

How to get all mathematical symbols on this editor without latex code

Just testing ${\log _a}n = \frac{{{{\log }_b}n}}{{{{\log }_b}a}}$. And one more time $${\log _a}n = \frac{{{{\log }_b}n}}{{{{\log }_b}a}}$$
