We do plenty of math, so I’d like to test out MathJax support.
Here is an example of MathJax inline rendering — \( 1/x^{2} \). And here is a block rendering:
\[ r_{XY} = \frac{\mathrm{cov}(X,Y)}{\sqrt{\mathrm{var}(X)\mathrm{var}(Y)}} \]
Now, if we’d like to get serious, we’d do something involving multiline aligned equations, like \[
\begin{align}
\mathcal{N}(t, \mu, \sigma) &= \mathrm{normal} \newline
&= \frac{1}{\sqrt{2 \pi} \sigma} e^{-\frac{(t-\mu)^2}{2 \sigma^2}}
\end{align}
\]
or even an inline formula like \( \sum_{t=0}^{\infty} \frac{x^t}{t!} = e^x\).
Or we could try defining a command, like this. \( \newcommand{\water}{\mathrm{H}_{2}\mathrm{O}} \)
Buffer slides off the sides of our tubes like \(\water\) off a duck’s back.
