The previous section (Section 1) was a bit boring.

This paragraph has some inline math, a Diophantine equation, \(x^2 + \doubler{y^2} = z^2\text{.}\) And some display math about infinite series: \begin{equation*} \sum_{n=1}^\infty\,\frac{1}{n^2} = \frac{\pi^2}{6}. \end{equation*} Look at the XML source to see how LaTeX macros are employed universally across all possible output formats.
