What is LaTex A scripting language used for writing documents. Donald Knuth in 1978 develop a typesetting program Tex. LaTex is an extension of Tex. Like a programming language, and produces files (PDF, html, ps) Differences with Microsoft word: Microsoft Word: ‘What You See Is What You Get’ (WYSIWYG) LaTex: You cannot see the final document while you are typing (WYSIWYM)

Advantages It looks pretty It is fast Consistent in term of formatting. Good for long documents, such as dissertation and books. y = \frac{{n!}}{{k!\left( {n - k} \right)!}}p^k q^{n - k} = \left( {\begin{array}{*{20}c} n \\ k \\\end{array}} \right)p^k q^{n - k}

Advantages (Cont.) Stability and interchangeability (Office 97, Office 2000, ….) Most journals have their LaTeX styles file (just download and use them). Good bibliography management. Connection with statistical software (R and SAS) It is free!

Disadvantages Learning curve. Take a little bit longer to obtain working knowledge. Flexibility. Hard to customize. Trade-off: hard to learn, but powerful.

Get Started with some basics

Get Started \documentclass[12pt]{article} \begin{document} Hello world. This is my \emph{first} document prepared in \LaTeX. \end{document}

\documentclass \documentclass[12pt]{article} {report} {beamer} {book} {letter} \documentclass[12pt]{article} article: suitable for short document, journal articles report: good for longer document, such as thesis. beamer: similar to power point format.

Standard Environments \begin{env_name} stuff \end{enc_name} Environment name (env_name) can be document, itemize, enumerate, tabular, etc. \begin{itemize} \item The first item \item The second item \end{itemize} \begin{enumerate} \item The first item \item The second item \end{enumerate}

Standard Environments \begin{equation} E=mc^2 \end{equation} \begin{tabular}{l|c|r} 1 & 2 & 3 \\ 4 & 5 & 6 \\ \end{tabular}

Figures \begin{figure} \centering \includegraphics {name of the figure file} \caption{Put the caption here} \end{figure} You can insert figures in pdf, jpg, png, eps, and other formats into your document. In general, figures have to be in the same folder as .tex file. Multiple figures can be inserted using \subfigure https://en.wikibooks.org/wiki/LaTeX/Floats,_Figures_and_Captions https://www.sharelatex.com/learn/Inserting_Images

Labels and cross-reference \begin{figure} \centering \includegraphics {name of the figure file} \caption{Put the caption here} \label{a short name that you can easily remember} \end{figure} \section{Introduction} \label{sec:intro} \section{Methodology} \label{sec:meth} …. In Section \ref{sec:intro}, we see the Figure \ref{fig:s11},

Math Mode

Math Mode Use \( … \) or $...$ for in-line math formulas Use \[ … \] or $$...$$ for math formulas with separate line Spaces inside \( … \) and \[ … \] are ignored. If needed, use “\ ” or “~” to add space Use \mbox{…} or \text{…} for words inside math formulas \begin{equation} …. \end{equation}

Math Mode: some examples x = \frac{-b \pm \sqrt{b^2-4ac} } {2a} \int_0^\infty \frac{\partial u}{\partial x} \gamma, \pi, \theta, \lambda, \sigma \Gamma, \Pi, \Theta, \Lambda, \Sigma https://oeis.org/wiki/List_of_LaTeX_mathematical_symbols http://artofproblemsolving.com/wiki/index.php?title=LaTeX:Symbols

Bibliography and Citation

Simple Bibliography If you know you have between 10 and 99 publications, you can start with \begin{thebibliography}[99]. Use any two digit number in the argument, since all numerals are the same width.

Bibliography Management BibTeX is a widely used bibliography management tool in LATEX. The bibliography entries are kept in a separate file and then imported into the main document. Once the external bibliography file is imported, the command \cite, \citet, \citep,… Very useful to build your own bibliography library. Make sure include package \usepackage{natbib}

Main Tex Ths document is an example of BibTeX using in bibliography management. Three items are cited: \textit{The \LaTeX\ Companion} book \cite{latexcompanion}, the Einstein journal paper \cite{einstein}, and the Donald Knuth's website \cite{knuthwebsite}. The \LaTeX\ related items are \cite{latexcompanion,knuthwebsite}.   \medskip   \bibliographystyle{unsrt} \bibliography{sample}

BibTex @article{einstein, author = "Albert Einstein", title = "{Zur Elektrodynamik bewegter K{\"o}rper}. ({German}) [{On} the electrodynamics of moving bodies]", journal = "Annalen der Physik", volume = "322", number = "10", pages = "891--921", year = "1905", DOI = "http://dx.doi.org/10.1002/andp.19053221004" }   @book{latexcompanion, author = "Michel Goossens and Frank Mittelbach and Alexander Samarin", title = "The \LaTeX\ Companion", year = "1993", publisher = "Addison-Wesley", address = "Reading, Massachusetts" }   @misc{knuthwebsite, author = "Donald Knuth", title = "Knuth: Computers and Typesetting", url = "http://www-cs-faculty.stanford.edu/\~{}uno/abcde.html" }

Another Advantages The bibTex file can be downloaded directly from Temple library Website!!!

Other Usage of Latex

Connect LaTex with other software Connect with R. Provide flexible and fast report writing and editing. Need two packages, kinitr and sweave. If you are all interested in learning R, we can do a section latter.

LaTex for Presentation Good for math intensive presentation. Not flexible LaTex for CV
