What is Latex?

Getting started with LaTeX

LaTeX can be run on different operating systems, including Windows, macOS, and Linux. Installations like TeX Live or MiKTeX on Windows, MacTeX or BasicTeX on macOS, and texlive package on Linux facilitate LaTeX usage.

Online platforms like Overleaf and ShareLaTeX offer browser-based LaTeX editing and compilation, eliminating the need for local installations. These platforms provide collaborative features and access to various templates.

LaTeX code structure

To begin writing a document in LaTeX, important components need to be understood and utilized effectively.

\documentclass{article}: Declares the document class, which determines the overall structure and formatting of the document.
Packages: Additional packages can be included to extend LaTeX's functionality. They are typically declared using the \usepackage{} command and can provide features such as mathematical symbols, graphics, and more.
\title, \author, and \date: These commands set the title, author, and date of the document, respectively. You can customize these elements as per your requirements.
\begin{document} and \end{document}: These mark the beginning and end of the document, respectively. Everything between these commands is considered the document content.
\maketitle: This command generates the title based on the information provided using \title, \author, and \date.
Sections and Subsections: Sections and subsections help structure the document. They are declared using \section{} and \subsection{} commands, followed by the respective heading title.
Conclusion: The concluding section wraps up the document and provides a summary or final thoughts.

Here is a straightforward example of LaTeX code that includes all the essential elements needed for a basic document.

\documentclass{article}
\title{My First LaTeX Document}
\author{Your Name}
\date{\today}
\usepackage{amsmath}
\begin{document}
\maketitle
\section{Introduction}
This is the introduction section of my document. LaTeX is a powerful typesetting system for creating professional-looking documents.
\subsection{Educative}
Educative provides interactive and adaptive courses for software developers with pre-configured developer environments in the cloud.
\section{Conclusion}
In conclusion, LaTeX provides excellent control over document formatting and is widely used in academic and technical writing.
\end{document}

\documentclass{article} % Document class declaration
\title{My First LaTeX Document} % Title of the document
\author{Educative.io} % Author's name
\date{\today} % Date
\begin{document} % Begin the document
\maketitle % Generates the title
\section{Introduction} % Section heading
This is the introduction section of my document. LaTeX is a powerful typesetting system for creating professional-looking documents.
\section{Mathematical Expressions} % Another section
Here are a few examples of mathematical expressions:
\subsection{Equation} % Subsection heading
The quadratic equation is given by:
\begin{equation}
    ax^2 + bx + c = 0
\end{equation}mple of a 
\subsection{Fraction} % Another subsection
A fraction example:
\begin{equation}
    \frac{1}{2} + \frac{3}{4} = \frac{5}{4}
\end{equation}
\subsection{Square Root} % Another subsection
The square root of a number:
\begin{equation}
    \sqrt{16} = 4
\end{equation}
\subsection{Summation} % Another subsection
Summation of a series:
\begin{equation}
    \sum_{i=1}^{n} i = \frac{n(n+1)}{2}
\end{equation}
\section{Conclusion} % Another section
In conclusion, LaTeX provides excellent control over document formatting and is widely used in academic and technical writing.
\end{document} % End the document

LaTeX boiler code

The document contains a title, author, and date. It consists of two main sections: Introduction and Mathematical Expressions. The Mathematical Expressions section includes examples such as a quadratic equation, fraction, square root, and summation. Lastly, there is a Conclusion which ends the document.

Output

When you compile the above LaTeX code, it will generate an output that is a formatted document. The mathematical expressions are presented formally, demonstrating the professional appearance of the output.

LaTeX features

LaTeX is a powerful tool that is commonly used in research papers for subjects like mathematics and physics. It excels in handling complex mathematical expressions and specialized formatting that regular word processors may struggle with.

Here are a few features of LaTeX:

Mathematical typesetting: It extensively supports mathematical equations, symbols, matrices, and notations.
Cross-referencing: It allows easy referencing of figures, tables, sections, and other elements within the document.
Bibliography management: Provides tools for managing bibliographic references and automatically generating bibliographies.
Customization: Allows users to define their document classes and customize styles, layouts, and formatting according to their needs.
Platform independence: Available on multiple operating systems (Windows, macOS, Linux) and can be used with various text editors.

Conclusion

LaTeX offers precise control over document formatting, making it an excellent choice for academic, scientific, and technical writing.
