LaTeX in blog posts

Sometimes I would like to include equation into the blog post. I claim that LaTeX is perfect for this job! However, one can not just type LaTeX code directly on Blogger. Wordpress has a plugin for this job. What can Blogger users use? I found the following:

• LaTeX for Blogger
  
• jsTeXrender
  
• LaTeXMathML

I wil try the jsTeXrender since they have a nice installation howto!

Now let us try with double $ tags: $$\Pr\left(A_1\right)=\frac{1}{2}$$

with pre tags:

\Pr\left(A_1\right)=\frac{1}{2}

and with code tags: \Pr\left(A_1\right)=\frac{1}{2}
