The basics


An example of an inline equation: \(a+b=\alpha\gamma\). To display an equation, you use the equation environment.

\begin{equation} \label{e.Newton}\left(\frac{\partial^{2}x}{\partial t^{2}}\right)=-\frac{GM}{r^{2}}\\ \end{equation}

We can also do display math without an equation number:

\begin{equation} G_{\mu\nu}=8\pi T_{\mu\nu}.\nonumber \\ \end{equation}

The equation environment allows us to cross-reference equations: equation (\ref{e.Newton}) is Newton’s equation. Citations are handled with the cite command and its variants: “observations of the quiescent luminosity of MAXI J0556-332 suggest the presence of a strong heat source in its accreted envelope (Deibel 2015).” Notice that this style uses an author-date system. With author-date, there are fancier versions of the cite command: “with the release of the second MESA paper, Paxton et al. (2013)”. Here I would like to cite this result (Deibel 2016).
