# Latex style guide

1. Do not use any indenting or tab in the tex files.
2. Do not put explicit line break using \\ unless you have a really good reason to do so.
3. A blank line creates a new paragraph. Put a blank line only if you need a new paragraph.
4. Do not use bold font unless really needed to highlight an important point.
5. Section headings must be lower case except the first letter and proper nouns
\section{Rising thermal bubble}

6. How to put a figure
\begin{figure}
\begin{center}
\includegraphics[width=0.8\textwidth]{figure}
\caption{This is a figure}
\label{fig:figlabel}
\end{center}
\end{figure}

DO NOT PUT FILENAME EXTENSION.
7. Always use \textwidth to specify figure size.
8. NEVER specify both width and height, unless you have a really good reason to do so.
9. Figure file formats must be either eps or pdf; NEVER use png or jpg files.
10. Use tabular within figure to put several figures side-by-side
\begin{figure}
\begin{center}
\begin{tabular}{cc}
\includegraphics[width=0.48\textwidth]{fig1} &
\includegraphics[width=0.48\textwidth]{fig2} \\
(a) & (b)
\end{tabular}
\caption{This is a figure: (a) pressure, (b) Mach}
\label{fig:figlabel}
\end{center}
\end{figure}

The sum of widths must not exceed one.
11. How to put a table
\begin{table}
\begin{center}
\begin{tabular}{|c|c|c|}
\hline
% other stuff
\hline
\end{tabular}
\caption{This is a table}
\label{tab:tablabel}
\end{center}
\end{table}

12. Do not use [h] or [ht] for tables and figures; they must be allowed to float.
13. Do not use ~, \hspace and \vspace unless it is absolutely required. Spacing must be automatically determined by Latex.
14. Equation, figure and table labels must be of the form \label{eq:foo}, \label{fig:foo}, \label{tab:foo}, respectively.
15. While quoting figure, table, etc., add a tilde to make the number appear on same line.
as shown in figure~(\ref{fig:foo}), the solution ...
as shown in table~(\ref{tab:foo}), the solution ...

16. Do not put comma/dot/period/full stop at end of equations.
17. A un-numbered equation can be put as
$a = b + c$

or
\begin{equation*}
a = b + c
\end{equation*}

18. Inline math must be completely enclosed in dollars
... and the EOS is $p = \rho R T$ ...
... where we use the value $\gamma = 1.4$ and $R = 1.0$ in the computations ...

19. To put space in equation
$a = b + c, \quad x = y + z$

To put more space
$a = b + c, \qquad x = y + z$

20. To use bigger brackets do
a = \left[ 1 + \frac{1}{2}b \right]

Do not use \bigg[, etc.
21. To use bold math fonts, use the bm package and then
\bm{v} = \frac{d \bm{x}}{dt}
