Testing how MathJax was hooked up

See http://www.math.toronto.edu/courses/apm346h1/20129/about_mathjax.html Note: If you have text snippet inside of math you should use \text{Your text} rather than format it as math as you did. You can also use \textrm{Your text}, \textit{Your text}. Also DoubleDollars are deprecated in LaTeX, you use \[ or \begin{equation*} \end{equation*} (without * for a numbered version)

PS I disabled  and  as they in the forum environment have funny side effects.
