# An Introduction to Latex

Latex is a typesetting system that was designed by Leslie Lamport in 1985.

Latex is a high-quality typesetting system; it includes features designed for the production of technical and scientific documentation. Latex is the de facto standard for the communication and publication of scientific documents. Overleaf is a good tool for this purpose. It offers an online LaTeX editor with real time preview, auto completion, templates in many fields like Mathematics, Statistics, Computer Science and Economics.

However, due to its design goals, it has more features specialised for documents with a complex structure, such as academic articles, than simpler designs like that of plain TeX or that of most word processors. In fact, in order to create beautiful and professional documents, it requires some knowledge and skills. In this blog we want to share our experience with latex (mainly overleaf) users who have just started using latex or are beginners in this field. We will try to explain the basic commands one by one and provide you with templates for different fields. Also we will describe our own experience using this amazing typesetting system.

We have created several templates including sample text which will help you start writing yours articles on overleaf using latex easily!

Latex is a typesetting system that makes it easy to add mathematical equations, tables, references and many other types of professional looking content to your documents. Latex is free and runs on all major operating systems.

Latex is a typesetting system widely used in academia for writing academic papers. It is a markup language with many useful features and helps to produce high quality documents. It is a very powerful and efficient way of writing documents. This blog is about the most useful features of latex and using them effectively.

Latex uses Latex compiler to generate the output file which can be converted into any other format like pdf, html etc. There are many latex compilers available free of cost on the internet like Miktex, Texmaker etc. One can download any of these compilers according to his/her liking.

Latex has many more features than I have discussed here, but these are the most important ones that can help you write great documents in an easy way without wasting too much time on formatting.

Latex is a typesetting system used by many publishers, scientists and mathematicians to format and display complex mathematical equations and formulas. Latex can also be used to typeset other areas of text, such as reports, essays, brochures and even books.

Latex consists of two parts: a ‘front end’ (as an editor) which allows users to create Latex documents using symbols and markup commands, and the ‘back-end’ which converts the user’s input into the final forma

\documentclass[12pt]{article}

\usepackage{amssymb,amsmath, latexsym}

\usepackage{fullpage}

\usepackage[ps2pdf=true]{hyperref}

This is a guide for your first latex document. This assumes you have already downloaded some version of latex onto your computer and know how to compile. If not, I strongly recommend MikTeX which is available at http://miktex.org/ . For more guides on how to use Latex check out http://www.latex-tutorial.com/ . There are also many other helpful websites for learning about Latex.

Here is an example Latex file:

\begin{document}

Hello World!\\

This is my first latex document!\\

$$\int_{-\infty}^{\infty} e^{-x^{2}}dx=\sqrt{\pi }$$

\end{document}

In order to make a new line in a document, you must use the command \text backslash textbackslash. The first line of code, \text backslash documentclass[12pt]{article}, tells the computer that

LaTeX is a powerful typesetting system based on TEX, a typesetting program developed by Donald Knuth. LaTeX is a standard set of macros that simplifies the usage of TEX. Although it is possible to create documents using plain TEX commands, it is recommended to use LaTeX along with plain TEX. Plain TEX can be used when you need to customize your documents and/or use programming techniques to automate the creation of your document.

The biggest advantage of using LaTeX over other text-based typesetting systems such as plain TEX, or Microsoft Word is that it allows you to focus more on the contents of the document rather than its appearance. This will allow you to concentrate on the idea behind each sentence, paragraph or chapter instead of worrying about the spacing between words, sentences or paragraphs; which font size should I use; whether I should use bold letters or italics in this part and so on.

LaTeX will take care of all these because it is a document markup language which uses special commands for marking up your document. In order to compile your LaTeX file, you will need two programs: A LaTeX distribution and an editor (or integrated development environment).

\documentclass[11pt,a4paper]{article}

\usepackage[utf8]{inputenc}

\usepackage[T1]{fontenc}

\usepackage{lmodern}

\begin{document}

When $$a \ne 0$$, there are two solutions to $$ax^2 + bx + c = 0$$ and they are

$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$

\end{document}
