\section{SageTeX and \texttt{latexmk}}

\texttt{latexmk} is a versatile utility for building \LaTeX documents.
It automatically learns about the inter-dependencies of all
documents and generated intermediate files.
It uses this information to run and repeatedly re-run various tools 
to produce a working final document.

To make it work well with SageTeX,
the file \texttt{latexmkrc} in the current directory defines
additional dependencies and instructions.

For more information, type a terminal \texttt{man latexmk}.

To enable SageTeX in combination with \texttt{latexmk},
this page explains how to modify the \texttt{latexmkrc} file:

Little caveat: to make it work in this demo,
a small wrapper script ``\texttt{run-sagetex.py}''
handles the filename and calling in order to work with SageTeX
correctly.

\section{SageTeX Demo}

1 + 1 = \sage{1+1}

% this is only processed in SageMath and not displayed
\begin{sagesilent}
x = var('x')
ex = (1 + x)^5
exe = ex.expand()
\end{sagesilent}

$\sage{ex} \rightarrow \sage{exe}$

Raw Strings:

\sagestr{str(CartesianProduct(['a', 'b'], [1, 2, 3]).list())}

Defining a function g:

\begin{sageblock}
a = 2
b = 3
x = var('x')
g = a * sin(b * x) + sqrt(x)
\end{sageblock}

And a plot of $g = \sage{g}$ from $[0, 10]$:

\sageplot[width=.5\textwidth]{plot(g, 0, 10)}
