What is LaTex
• LaTeX pronounced as “tech”
• not like latex gloves!
• LaTeX is a document preparation system for producing
professional-looking documents, it is not a word processor.

Introduction
• TeX is essentially a Markup Language (like
HTML, XML and RTF)
• TeX written by Donald Knuth in 70´s
– A revolution in typesetting
• Latex is an extension of TeX
– Macro packages to make TeX easier to use

Latex vs. Word Processors
• High typeset quality
• Easy to include math formulas
• Source file format is not bounded to a particular
OS or platform
• Latex implementations exists for all platforms
(DOS, Windows, Unices,..)
• Latex is free

Latex vs. Word Processors
• De facto standard for scientific publishing
• Very few bugs
• Good for large documents
• Can run even on 386 PC
• Not very easy to learn

Getting Started
– Windows

– Linux
• TeXLive
– Mac

Mathematics command
$$  for Mathematics Symbols
^  used for Power
_  used for Indices

sqrt{---}  for Square root
sum  for Summation
int  for integration
$Delta$ =∆
$Pi$ = ∏
$Sigma$ = ∑
$Omega$ = Ω

Mathematics in LaTex
begin{document}
$$sqrt{y^2}$$
begin{eqnarray}

a & = & b + c
& = & y - z
end{eqnarray}
$$sum_{x=1}^5 y^z$$
end{document}

Advantages of LaTeX
• Professional typesetting
– Best output
• It is the standard for scientific documents
• Processing Mathematical (& other) symbols
• Meaning based structuring (rather than appearance)
• Knowledgeable and helpful user group
• Its FREE!
• Platform independent

Disadvantages of using LaTeX
• “Hard to write disorganized documents”
• Learning Curve
• Customizing is tedious.

Conclusions
• Latex is optimal for master and phd thesis
• Mathematical formulae are easy.
• Consider converting Postscript files to PDF (more
widespread in Windows world) and to conserve
space.
