I'm trying to use LaTeX on my blog, but I could not figure out how. Has anyone done it before? Any feedback or related information would be greatly appreciated.

You might want to give us more detail, for example whether you are using a hosted blog, the blog software and version, etc. – Joseph Wright♦ Mar 19 '11 at 9:41

@Joseph: Presumably blogspot. – TH. Mar 19 '11 at 9:49

Very much related: LaTeX in Blogger (possible duplicate?). – Hendrik Vogt Mar 19 '11 at 12:21
@Hendrik: they are very much related, but the related question hasn't been marked as answered. Now that mathjax has a CDN, the top-voted answer in the related question is outdated (and was incomplete anyway). So if Chan is successful with this, I the older question should be closed as a duplicate of this one. – Matthew Leingang Mar 19 '11 at 13:33
@Matthew: That sounds like a good idea. – Hendrik Vogt Mar 19 '11 at 13:43

I would say use MathJax. It's a AJAX engine for LaTeX syntax that now is distributed by a CDN so you don't have to upload a single file to your blogspot account.

Googling "install mathjax blogspot" led me to a page “LaTeX using MathJax on Blogger”, which seems to have instructions:

To enable MathJax, just drop in

<script type="text/javascript" src="http://cdn.mathjax.org/mathjax/latest/MathJax.js">
MathJax.Hub.Config({
 extensions: ["tex2jax.js","TeX/AMSmath.js","TeX/AMSsymbols.js"],
 jax: ["input/TeX", "output/HTML-CSS"],
 tex2jax: {
     inlineMath: [ ['$','$'], ["\\(","\\)"] ],
     displayMath: [ ['$$','$$'], ["\\[","\\]"] ],
 },
 "HTML-CSS": { availableFonts: ["TeX"] }
});
</script>

after the header (<head>) in the Blogger template (Design→Edit HTML→Edit Template).

See the MathJax pages for more information about configuring and using it.

Awesome, thanks a lot. – Chan Mar 19 '11 at 21:43
@Chan: did you end up doing it this way? Did it work? If so, you can click the green check and we'll merge the older question into this one. – Matthew Leingang Mar 22 '11 at 11:41
This helped me get $\LaTeX$ on my blog, thank you. What more, the same trick works for comments as well, provided they appear on the same page as the post! – gphilip May 17 '11 at 2:37

The page of instruction pointed is now unavailable: "El blog se ha eliminado. Lo sentimos, el blog de mnnttl.blogspot.com se ha eliminado. Esta dirección no está disponible para blogs nuevos." – Jeremy Jul 6 '11 at 13:22
