Why LATEX? The advantages of LATEX
Advantages of LATEX It is a free software. Available for most of the machines. Relatively easy to typeset (specially when mathematics is involved). Easy to handle large documents.

Why not LATEX? The disadvantages of LATEX
Disadvantages of LATEX A high level of LATEX understanding is required for handling unstructured documents. Using custom fonts is not straight forward. WYSIWYG(What You See Is What You Get) editors are not available. Some partial WYSIWYG are available (I do not recommend).

Getting ready with the LATEX platform Online: ShareLaTeX Log-in with your credentials. Create a new blank project (this is similar to creating a folder in a PC) “practice”. Getting familiar with the environment.
TeXLive installed on PC Create an empty folder, name it “practice”. Open TeXStudio, create a new document (“main.tex”) inside the newly created folder. Getting familiar with the environment. *A LATEX file is a normal text file with .tex extension. S. K. Gadi (FIME-UT, UAdeC)

My first article with LATEX A simplest LATEX document \documentclass{article}
\begin{document} Hello {\LaTeX} \end{document} The entire LATEX code can be divided into preamble and the document environment. Considering the convenience of the user, unlike the other software, Text does not require special notation whereas LATEX commands require special notation (i.e. \). S. K. Gadi (FIME-UT, UAdeC)

Compile and see the difference from the original text.
LATEX functions and importance of { } and [ ] \usepackage[utf8]{inputenc} In a LATEX function { } contains obligatory arguments, [ ] contains optional arguments. Make changes to the project “practice”

Using mathematics environment “equation” environment \begin{equation} x=\frac { -b\pm \sqrt { { b }ˆ{ 2 }-4ac } \end{equation}
}{ 2a }
“eqnarray” environment \begin{eqnarray} x &=& \frac{-b\pm\sqrt{{b}ˆ{2}-4ac}}{2a}\\ &=& \frac{-b}{2a}\pm\frac{\sqrt{{b}ˆ{2}-4ac}}{2a} \end{eqnarray} *The above equations are generated with the help of “Daum Equation Editor”
The symbol (or keyword) “&” represents tabspacing and “\\” skips to the next equation. S. K. Gadi (FIME-UT, UAdeC)

Making reference to figures, tables, equations etc. The concept is to generate a unique key (\label{}) the environment you want to cite. It can be a section, part, chapter, figure, table, or equation etc. The unique key can be used to refer (\ref{}) at any point of the document.
Put a unique key in the figure environment \begin{figure} \centering \includegraphics[width=8cm]{sample-image-000} \caption{A random picture.} \label{AUniqueKey} \end{figure}
Use the command “\ref” to refer the label A random image is shown in Figure \ref{AUniqueKey}. S. K. Gadi (FIME-UT, UAdeC)

Use \autoref Include the package “hyperref” in the preamble \usepackage{hyperref} Make sure \usepackage{hyperref} is used after \usepackage[spanish,mexico]{babel}. Use \autoref{key} instead of \ref{key}.
Exercise (15 min maximum) Make an article of 3 sections with the first and the last sections containing 1 figure, 1 equation and 1 table. In the second section, write a text and refer the figures, sections, tables and equations. Use both \autoref and \ref to see the difference.
