Basic usage and packages of TEX

1. Basic usage and packages of TEX Sung-Ju Kang Department Of Physics Kangwon National University TEX is a computer program for typesetting documents. CONTENTS (1) Input Files (2) Input Files Structure (3) Big Projects

2. Input Files • 1) The input for LATEX is a plain text file. • 2) Compiled the input file. • $ latex filename.tex • 3) Obtain the `DVI' file, to can print out. • 4) The `DVI' file is Changed to the ‘PS’ and ‘PDF’ file. • Making the ‘PDF’ file that used the ACROBAT. $ dvipdfm filename.dvi • Making the ‘PS’file that used the GHOSTVIEW. $ dvips filename.dvi

3. (2) Input Files Structure • \documentclass{….} • This specifies what sort of document you intend to write. • 2) \usepackage{….} • You can include commands which influence the style of the whole document, or you load packages which add new features to the LATEX system. • 3) \begin{document} • Now you enter the text. • 4) \end{document} • This command tells LATEX to call it a day.

4. 1) \documentclass[option]{class} {class} specifies the type of document to be created. • article : for articles in scientific journals, presentations, …. • report : for longer report containing several chapters, small book, …. • book : for real book • slides : for slides [option] parameter customizes the behavior of the document class. The option have to be separated by commas. • 10pt(default), 11pt, 12pt : Size of main font in the document. • a4paper, letterpaper,.. : Defines the paper size. • titlepage, nontitlepage : Specifies whether a new page should be started after the document title or not. • oneside(default), twoside : Whether double or single sided output shoud be generated.

5. 2) \usepackage[option]{package} {package} parameter is a name of the package. • dos : Allows the documentation of LaTeX programs. • hangul : Allows to use of the ‘The Korean alphabet’. • exscale : Provides scaled versions of the math extension font. • fontenc : Specifies which font encoding LaTeX should use. • latexsym : To access the LaTeX symbol font. • makeidx : Provides commands for producing indexes. • syntonly : Processes a document without typesetting it. • inputenc : Allows the specification of an input encoding. [option] parameter is a list of keywords which trigger special features in the package.

6. 3) \begin{document} • LATEX Commands They consist of a backslash and exactly one special character. • Comments When LATEX encounters a % character while procession an input file, it ignores the rest of the present line and the line break. • Typesetting Mathematical Formulae LATEX has a special mode for typesetting mathematics. · Mathematical text within a paragraph is entered between \ [and \], $ [and $], \begin{math} and \end{math}. · It is preferable to display larger mathematical equations or formulae. This means you enclose them in \ [and \] or \begin{displaymath} and \end{displaymath}. This produces formulae which are not numbered. If you want LATEX to number them, you can use the equation environment.

7. (3) Big Projects When working on big documents, you want to split the input file into several parts. \include{filename} You can use this commend in the document body to insert the contents of another file named filename.tex. Note that LaTeX will start a new page. \includeonly{filename, filename,…} This command can be use in the preamble. After this command is executed only listed in the argument of the \includeonly command will be executed. \input{filename} This command simply includes the file specified. No flashy suits, no strings attached.

8. SUMMARY • TEX is a computer program for typesetting documents. • Input text file is changed the ‘DVI’ file, ‘PS’ file and ‘PDF’ file. • Input file consists of the special structure and you enter the text mixed with some useful LATEX commands. • You can work to split the input file several parts.
