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.
 set blogger.com template to "Simple". "Dynamic Views" seems not working.

edit HTML by adding the following code between
<head>
and</head>
.
<script src='http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeXAMSMML_HTMLorMML' type='text/javascript'/>

type math equation in the blog.
\(
" and "\)
" 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
\[z=\sqrt{x^2+y^2}\]
