Using MathJAX

MathJAX is a javascript that allows you to use TeX and MathML code in your HTML pages, and have those formulae displayed correctly.

Here's a MathML example:

a2+b2=c2

You simply create HTML blocks using $MathML formulae$.

Here's another example, demonstrating matrices:

A=xyzw

Your browser should display a 2x2 matrix above this text.
Make sure your TinyMCE plugin settings are set to NOT clean code on save.

Here's a more complicated formula for standard deviation:

σ=1N∑i=1N(xi−μ)2.

Here's the curl of a vector field:

∇→×F→=(∂Fz∂y−∂Fy∂z)i+(∂Fx∂z−∂Fz∂x)j+(∂Fy∂x−∂Fx∂y)k
