# Let me do the math...

One of my least favorite phrases. But let's see if this works:

\[ f_{X}(x) = \frac{1}{\sqrt{2 \pi \sigma^{2}}} e^{-\frac{1}{2 \sigma^2} (x - \mu)^2}\]

Yep. That's the probability density function for a normal random variable, \( X \sim N(\mu, \sigma^{2}) \). The most math-y thing I could think of at the moment. Which shows you were my head is at.

PS - The formulas in this post were generated using MathJax. Not quite as pretty as LaTeX, but it at least uses the same formatting.
