NICE!
I'm using the MathJax content delivery network; well, actually, the secure connection (of course). Once that is done, then
$$...$$
or \[...\]
delimit displayed mathematics, and \(...\)
delimits in-line math. What should also work is right-clicking the image to see the source, although that may only function if MathJax is installed locally.
Regardless, this should make it easier to display mathematics on the web, and should obviate the need to have images rendered as gifs and loaded (as can be seen in previous posts. Maybe I'll post a bit more often now!
Testing MathJax in comments. ∑ni=1n=n(n+1)2
n∑i=1n=n(n+1)2
