### MathJax with Blogger

MathJax in blogger.com is useful when I need to input equation in my blog. This is a instruction and test of using MathJax in blogger.com.
1. set blogger.com template to "Simple". "Dynamic Views" seems not working.
2. edit HTML by adding the following code between <head> and </head>.
<script src='http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML' type='text/javascript'/>

3. type math equation in the blog.
Note that, enclosing math in single \$'s does not work. Instead, I use "$$" and "$$" for inline math and "$" and "$" for displayed math. For example:
$$\frac{2}{3}$$

will show an inline math "$$\frac{2}{3}$$", and
\$z=\sqrt{x^2+y^2}\$

will show a displayed math $z=\sqrt{x^2+y^2}$
