# Using the LaTeX Plugin for Mathematical Formulas

http://wordpress.org/plugins/latex/

A plugin has been added that allows the writer to utilize LaTeX mathematical commands to build up formulas for their web site. As an example see the following output.

An "in-line" formula

This is an in-line $\alpha+\beta\geq\gamma$ equation.

Adds a LaTeX equation in math model which will be displayed in its own line (Centered).

The following code produces the matrix below:
$\mathbf{V}_1 \times \mathbf{V}_2 = \begin{vmatrix} \mathbf{i} & \mathbf{j} & \mathbf{k} \\ \frac{\partial X}{\partial u} & \frac{\partial Y}{\partial u} & 0 \\ \frac{\partial X}{\partial v} & \frac{\partial Y}{\partial v} & 0 \end{vmatrix}$

A Rogers-Ramanujan Identity

 $1 + \frac{q^2}{(1-q)}+\frac{q^6}{(1-q)(1-q^2)}+\cdots = \prod_{j=0}^{\infty}\frac{1}{(1-q^{5j+2})(1-q^{5j+3})}, \quad\quad \text{for |q|<1}.$

More demos can be found at http://www.mathjax.org/demos/tex-samples/

The plugin uses the "MathML" and "LaTeX" and a Javascript code called "MathJax" to render the equations.
