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

Does Math like

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

let's try:

$\mathcal{M}[f] (s) = \int_0^{\infty} x^{s - 1} f (x) dx .$

$\mathcal{M} \left[ \frac{d}{d x} f (x) \right] = - (s - 1) F (s - 1),\quad \mathcal{M} \left[ x^{\mu} f (x) \right] = F (s + \mu) .$

$\sum_{k=0}^{p-1} C_kx^k\equiv \frac{1-(1-4x)^{(p+1)/2}}{2x}-x^{p-1}\quad\bmod (p,x^p).$

Give it a try - post some "answers" and see how it works for you.

edit: here are instructions to enable MathJax.

There is a caveat - if you right-click and choose some setting - django may sign you out. It's due to the bug in python Cookie module or MathJax cookie name. MathJax wants to set up cookie named mjx:menu, but python does not like : in the name. I have found the place in MathJax where that character can be replaced with say -, but rebuilding MathJax is not trivial - not all build scripts are present in the repository.

If the site "kicks you out" this way - delete cookie for askbot.org named as above and re-signin.

This issue in MathJax will hopefully be solved very soon.

mathjax now works in wmd preview, somewhat slow with large equations though.

I dont see any formulas but only pure LaTex script, or is math not enabled on this installation?

Tuta, we will fix this tomorrow, some things got out of hand when we migrated some software. Mathjax should work fine. It works on http://ask.sagemath.org running a bit older version of askbot.

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 $\text{Sim}({{\mathbb{R}}^{2n+1}})={{\mathbb{R}}^{2n+1}}\times (\mathrm{O}(2n+1)\times {{\mathbb{R}}^{+}})$ .

Bob, I've disabled the normal behavior of underscores, so math is rendered is more faithfully, but for the real fix the markdown parser will need to be updated. I'm now looking at how this can be done.

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.
