Why LaTeX?

LaTeX is not a word processor - it's a typesetting system that separates content from formatting. You write the text and commands, and LaTeX takes care of the perfect layout.

LaTeX Advantages:

• Perfect mathematical formulas - No other system does them better
• Consistency - Formatting is automatic and uniform
• Automatic bibliographies - BibTeX manages citations
• Academic standard - Required by journals and conferences
• Total control - You can customize any aspect

Basic Structure:

\documentclass[12pt]{article}

% Preamble - packages and settings
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{amsmath}

\title{Document Title}
\author{Your Name}
\date{\today}

\begin{document}

\maketitle

\section{Introduction}
This is my first LaTeX document.

\section{Mathematical Formulas}
Einstein's equation:
\begin{equation}
    E = mc^2
\end{equation}

\end{document}

Mathematical Formulas:

LaTeX excels at formulas. You can write inline with $...$ or display mode with \[...\]:

% Inline math
Let $f(x) = x^2 + 2x + 1$ be a quadratic function.

% Display math
\[
    \int_0^\infty e^{-x^2} dx = \frac{\sqrt{\pi}}{2}
\]

% Numbered equation
\begin{equation}
    \sum_{n=1}^{\infty} \frac{1}{n^2} = \frac{\pi^2}{6}
\end{equation}

% Fractions and limits
\[
    \lim_{x \to 0} \frac{\sin x}{x} = 1
\]
