Use Latex in Blog

Hi,

In order to use latex in Blog, one needs to follow a few steps. I saw this nice video while solving the problem.

Following are a few examples of the code which shows up right on the blog,


1. $$\begin{eqnarray} I &= & 1/3\int \frac{du}{\sqrt{u}(u+1)}\\ &= & 2/3\int \frac{2v\ dv}{v^2+1} \mbox { (Substituting } u=v^2 \mbox{we get } du = 2v\ dv)\\ &= & (2/3) \tan^{-1}(\sqrt{x^3-1}) \end{eqnarray}$$

2. $$\begin{equation} x=y\\ z=w \end{equation}$$
