Overview of this book

LaTeX is high-quality Open Source typesetting software that produces professional prints and PDF files. However, as LaTeX is a powerful and complex tool, getting started can be intimidating. There is no official support and certain aspects such as layout modifications can seem rather complicated. It may seem more straightforward to use Word or other WYSIWG programs, but once you've become acquainted, LaTeX's capabilities far outweigh any initial difficulties. This book guides you through these challenges and makes beginning with LaTeX easy. If you are writing Mathematical, Scientific, or Business papers, or have a thesis to write, then this is the perfect book for you. LaTeX Beginner's Guide offers you a practical introduction to LaTeX with plenty of step-by-step examples. Beginning with the installation and basic usage, you will learn to typeset documents containing tables, figures, formulas, and common book elements like bibliographies, glossaries, and indexes and go on to managing complex documents and using modern PDF features. It's easy to use LaTeX, when you have LaTeX Beginner's Guide to hand. This practical book will guide you through the essential steps of LaTeX, from installing LaTeX, formatting, and justification to page design. Right from the beginning, you will learn to use macros and styles to maintain a consistent document structure while saving typing work. You will learn to fine-tune text and page layout, create professional looking tables as well as include figures and write complex mathematical formulas. You will see how to generate bibliographies and indexes with ease. Finally you will learn how to manage complex documents and how to benefit from modern PDF features. Detailed information about online resources like software archives, web forums, and online compilers completes this introductory guide. It's easy to use LaTeX, when you have LaTeX Beginner's Guide to hand.

Writing theorems and definitions


LaTeX provides environment for theorems, definitions, and alike. Returning to our first example in this chapter, we could define a theorem environment by:

\newtheorem{thm}{Theorem}

Then, we declare a definition environment, using an optional argument stating an existing environment with which we would like to share the numbering:

\newtheorem{dfn}[thm]{Definition}

And in this simple way, we may use these environments:

\begin{dfn}
A quadratic equation is an equation of the form
\begin{equation}
  \label{quad}
ax^2 + bx + c = 0,
\end{equation}
where \( a, b \) and \( c \) are constants and \( a \neq 0 \).
\end{dfn}
\begin{thm}
A quadratic equation (\ref{quad}) has two solutions for the variable \( x \):
\begin{equation}
  \label{root}
  x_{1,2} = \frac{-b \pm \sqrt{b^2-4ac}}{2a}. 
\end{equation}
\end{thm}

In the output, such environments are numbered and labeled "Theorem" and "Definition", respectively. In Chapter 10, Developing Large Documents, when we are going...
