  1. INTRODUCTION TO LATEX Zheng Chen Southern University at New Orleans 11/11/2011 zchen@SUNO

  2. Outlines • What is Latex for? • Environment of Latex • Edit • Debug

  3. What is the Tex, Latex • LATEX is a typesetting system that is very suitable for producing scientific and mathematical documents of high typographical quality. • It is also suitable for producing all sorts of other documents, from simple letters to complete books • TEX is a computer program created by Donald E. Knuth about 1980’s, “TEX” pronounced “Tech” • Latex was originally written by Leslie Lamport; pdflatx different version.

  4. Steps to install latex soft wares • Download and install MikTeX ... this can take awhile. http://www.miktex.org/ • Download and install Ghostscript (and Ghostview if you want it) first. http://pages.cs.wisc.edu/~ghost/ • www.winedt.com download winEDT • Then download and install an editor. http://www.latexeditor.org/

  5. Special Characters • # $ % ^ & _ { } ~ \ • As you will see, these characters can be used in your documents all the same by using a prefix backslash: \# \$ \% \^ { } \& \_ \{ \} \~ {} \textbackslas

  6. Two formats on commands • LATEX commands are case sensitive • \sqrt{ }, \frac{ }{ }, \today \begin{aligns} \end{aligns} \newline \newpage • \& \$

  7. comments • % ignores all the rest of the line after % • Examples, in a tex file (save as .tex): % we will use later % reminder: please change data here

  8. Input file structure (file name .tex) • \documentclass{...} % option \usepackage{...} % option \begin{document} %contents input here \end{document}

  9. Example A \documentclass{article} \begin{document} % life is beautiful. \\ % \TeX is great.\\ % to practice Latex? easy!\\ Today is \today. \end{document}

  10. Input structure of an article \documentclass{article} \author{ } \title{} \begin{document} \maketitle \abstract \section \subsection \begin{thebibliography} \end{thebibliography} \begin{document}

  11. \documentclass[a4paper,11pt]{article} % example B \usepackage{amssymb} \author{S. Henry} \title{How to learn math well} \begin{document} \maketitle \begin{abstract} In this paper, we talk about how to learn math well through practice. \end{abstract} \section{Introductory } Practice makes perfect. \subsection{math history} Three math crises, irrational number $\sqrt{2}$, pure imaginary number $i$, and one more. \\ Please refer the books \cite{polya} and \cite{klein}. \begin{thebibliography}{99} \bibitem{polya} G. Polya: Mathematics and Plausible Reasoning, Volume 1: Induction and Analogy in Mathematics, 1990\\ \bibitem{klein} Morris Kline: Mathematical Thought from Ancient to Modern Times, Vol. 1 \end{thebibliography} \end{document}

  12. Math expressions • In one line with other words, use $ $, If we have an equation $(\sqrt{2}+ x)^2=3+2\sqrt{2}$, what is the $x$ value? • In a separate line, centered, use $$ $$ We have the following equation:\\ $$ (3x-5)(2x+y)=x^2-8 $$

  13. More math expressions • Systems of equations • Matrices • One more sample • Need a reference book, or just google to get help

  14. \documentclass[a4paper,11pt]{article} % example C \usepackage{amsmath} \author{S. Henry} \title{Learn Latex In One Hour } \begin{document} \maketitle \begin{abstract} In this paper, we talk about math expressions input in latex. \end{abstract} \section{math expressions in lines } In one line with other words, use \$ \$, If we have an equation $(\sqrt{2}+ x)^2=3+2\sqrt{2}$, what is the $x$ value? In a separate line, centered, use \$\$ \$\$ We have the following equation:\\ $$ (3x-5)(2x+y)=x^2-8 $$ Let us solve it. \subsection{more math expressions} solve a linear equation as follows:\\ \begin{align} &-x^2+2x-3 \\ &=-(x^2+2x)-3 \\ &=-(x^2+2x+1-1)-3\\ &=-(x+1)^2-2 \\ &\le -2 \\ &<0 \end{align}

  15. a piecewise function: \\ \begin{displaymath} f(x) = \left\{ \begin{array}{crr} 1 & \text{if $ x > 0$}\\ 0 & \text{if $ x =0$}\\ -1& \text{if $ x < 0$} \end{array} \right. \end{displaymath} Please refer the books \cite{polya} and \cite{klein}. \begin{thebibliography}{99} \bibitem{polya} G. Polya: Mathematics and Plausible Reasoning, Volume 1: Induction and Analogy in Mathematics, 1990\\ \bibitem{klein} Morris Kline: Mathematical Thought from Ancient to Modern Times, Vol. 1 \end{thebibliography} \end{document}
