$\LaTeX$ Test!

I'll be writing a lot of math, so being able to incorporate \(\LaTeX\) into my posts is essential. To this end I use MathJax, which allows you to write inline math expressions such as $\frac{1+\sqrt{-163}}{2}$ or standalone equations:
$$\frac{df}{dx} = \frac{1}{2} \left(\frac{ab \textrm{ sech}^2(b \sqrt{x})}{x} - \frac{a \tanh(b \sqrt{x})}{x^{3/2}} \right).$$

Hopefully these render once I get the MathJax plugin working properly...

[Edit] Looks like it's working!
