LaTeX in this blog!

Nicolas Monod — Mon, 14 Sep 2009 13:10:35 +0000

We can use some amount of in this blog. Just put any math command between $ signs, with the word “latex” (followed by a space) right after the first $.

Thus, for instance, if I write this:

$latex \sum_{n=1}^\infty \frac1{n^2} = \frac{\pi^2}6$,

you will see that:

Of course, only basic commands will work. Enjoy!
