### MathJax: LaTeX on Blogger - finally!

I am easily excited when I find yet another place where I can use LaTeX syntax to typeset mathematics (Google Docs, OpenOffice, again, presentations using BeamerInkscape).

Finally, it seems, it is not incredibly clunky to write math in Blogger. In fact, it is as convenient as writing it in a native LaTeX document.

The latest avataar of MathJax, while not really new, is new to me. Here are a few links which describe how to go about empowering your Blogger account.

The easiest permanent fix is to add some script in your Blogger template file, as described here.

If you don't like messing with your template, you can take the approach outlined here. Basically, you add some lines to each post in the "html" view, which has math in it.

Here is a mandatory test:
$\frac{df}{dx} = \frac{1}{2} \left(\frac{ab \textrm{ sech}^2(b \sqrt{x})}{x} - \frac{a \tanh(b \sqrt{x})}{x^{3/2}} \right)$
Beautiful!

Does this still work?
$$\sum_{n=0}^{N-1} x^n Sachin Shanbhag said...$$\sum_{n=0}^{N-1} x^n$$Anonymous said...$$\sum _{2}^{2}$$Giacomo Alzetta said... It doesn't seem to work anymore... At least I cannot see any LaTeX rendered. Not yet! said...$$\theta(x) = t$$Do we put a double$$ sign around the code, or how is it done.?

@Giacomo: Seems to work fine for me. Could it be your browser?
@NotYet: You got it!

As a matter of curiosity, I'm using MathJax with a 'Classic' Blogger template. And I'm inserting the necessary code in each post in which it is needed.

On blogger/blogspot there is a security feature that prevents the loading of http: links in https: content (like blogger/blogspot). I don't know if it's a new feature, but it can prevent latex rendering on some browsers. If you're having trouble, replace the url to the MathJax.js library with:
https://c328740.ssl.cf1.rackcdn.com/mathjax/latest/MathJax.js

It's not pretty, but it's a legit https link to the mathjax library. It is discussed on the official mathjax site here: http://www.mathjax.org/resources/faqs/#problem-https

Thanks, Albert.

No one is dumb who is curious. The people who don't ask questions remain clueless throughout their lives. See the link below for more info.
