# How to use LaTeX on blogspot?

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 Now that mathjax has a CDN, the top-voted answer in the related question is outdated (and was incomplete anyway).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
@Jasper: Because it was in the title of the question. –  TH. Jun 18 '11 at 8:20

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.

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).

Googling "install mathjax blogspot" led me to a page on the Web Applications StackExchange: MathJax on Blogger.

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
