# Mathematical Equations on EP

EP has a new feature! The ability to format mathematical equations via mimeTeX and primitive graphing from WZgrapher. LaTeX is commonly used by mathematicians as well as economists to format complex mathematical equations in Academic papers. Of course using HTML codes or good old fashioned export to image from Excel or even Matlab still works great on EP!

To figure out the syntax to display complex mathematical equations, you can start with the above links, the graph link is slightly more clear.

Then, this wikipedia on math markup gives some more short cuts on how to format mathematical formulas using LaTeX syntax. (Note, the syntax for the formulas should (pretty much) be LaTeX, this is a faster version for server CPU load reduction). Then, this howto on LaTeX has some basic mathematical symbols.

You wrap your LaTex syntax in  special tags.

Here is an example:

syntax:

$$\frac{\partial^2 y}{\partial x_1\,\partial x_2}$$

produces the partial derivative symbol:
$\frac{\partial^2 y}{\partial x_1\,\partial x_2}$
