This blog does not use MathJax. This blog was created to demonstrate how MathML can be rendered in blogger blogs in IE and Fire Fox. This blog still works in IE and Fire Fox. For IE, you will need MathPlayer. If using IE9, you may want to turn on the compatibility mode otherwise it won't render MathML even with MathPlayer installed.
I have created 2 blogs to demonstrate how one can use MathJax in blogger blogs to render MathML and also Tex. They are
Special Products Examples
The first blog shows the best way to include MathJax script in the headers. You can examine the headers to find that out.
The second blog is there to test out various Tex code using MathJax. To tell the truth, I don't know Tex and I want to learn Tex. So, the title of the blog is Learning Tex. This blog has Tex code only. And, it gets rendered fine just about in any browsers, IE, Fire Fox, Chrome and Safari to name a few. It crashes my old Palm T/X though.
