Today What and why Latex? Overleaf Introduction to Latex - Basic commands - Structure of the document - Mathematical expressions Homework #2
LaTeX A document preparation system developed by L. Lamport based on the TeX system created by D. Knuth. Takes a document created using the Latex markup language and converts into a format suitable for printing (typically PDF). Free software.
Latex (cont) Powerful support for mathematical formulas and diagrams, citations, cross-references, footnote, bibliographies, etc. Commonly used by publishers for preparation of books and academic journals. Flexible programming environment for creating new commands, environments, packages, etc.
Using Latex on your own computer Main Latex website: https://www.latex-project.org/ On MacOS: Install MacTeX: http://www.tug.org/mactex/ On Windows: Install MiKTeX: https://miktex.org/ Both distributions contain a complete system (including editor) Plenty of documentation online Easy to find help!
A few more links The Not So Short Introduction to LATEX 2ε https://tobi.oetiker.ch/lshort/lshort.pdf Wikibook on Latex https://en.wikibooks.org/wiki/LaTeX Possible to use Latex online (without installing anything) e.g. https://www.overleaf.com/
Latex vs. Word Advantage of Latex: - Portable: can be used on any computer - Stable: old documents can still be read - Standard in Academic world Easier to use but only after some time - Drawback of Latex: - Not WYSIWYG - Not so common outside of university - May be more difficult at the beginning
Latex – General Idea Focus on the content Do not focus on the design/layout Latex will choose automatically the best design How to use Latex: 1 – Write a source file “report.tex” 2 – Compile using Latex 2’ – Fix the errors and compile again 3 – Check the result, typically “report.pdf”

It seems complex but as we will the \begin{document} and see, it is not so difficult to write \end{document} commands good documents using Latex! The command \maketitle creates the top of \end{document} the document

It seems complex but as we will see, it is not so difficult to write good documents using Latex! \end{document}
Latex – Document structure ... \begin{document} Use the commands \section{…} \section{ How to use matplotlib } and \subsection{…} to structure I describe here how to use matplotlib your document. \section{ How to use \LaTeX } I describe here how to use LaTeX. I will first explain history of Latex, then some basic Use an empty line to start a new commands, then ... paragraph. New paragraph starts after an empty line. \subsection{ History } Bla bla bla bla Automatic numbering of sections and \subsection{ Basic commands } subsections Bla bla bla bla Try subsubsection or \subsection{ Something else } \end{document} subsubsubsection or …
Latex – List ... \begin{document} The itemize environment can be There are three main OS: used to create a list of items. \begin{itemize} \item macOS \item Linux To create numbered list, one should \item Windows use the enumerate environment. \end{itemize} There are three main OS: \begin{enumerate} \item macOS \item Linux Try enumerate on your computer. \item Windows \end{enumerate} Try nested lists on your computer. \end{document}
Latex – Math expressions ... \begin{document} Inline mathematical expression appears between $...$ It is very easy to write ``complex'' mathematical expressions. You can write Greek letters; for example $\alpha$ , $\beta$ , $\gamma$ , $\Gamma$ , \ldots It is also possible to write some mathematical Display mode is activated using \[ … \] and terms: $\sqrt{256} = 16$ or $x_1 + x_2 + x_3$ or should be used for more complex formulas $(x+y)(x-y) = x^2 - y^2$ . If you need bigger formula, you can use the display mode as follow: \[ Use the `` and '' for quotes. Do not use the “ \sum_{n=1}^{\infty} \frac{1}{n^2} = \frac{\pi^2}{6} (double quotation mark) \] \end{document} Note also the \ldots command that produces …
Homework #2 Create a simple Latex document that contains: - A title and your name (as author) - The mathematical expression on the right, including the parenthesis and the +/- sign. (you can look for help online) - A short text explaining the previous equation. Download the two files from Overleaf: ‘homework2.tex’ and ‘homework2.pdf’. Compress them in ‘homework2.zip’. Submit via OCW-i the compressed file before July 27 (23:50).
