  1. 157A, Fall Semester 2006 Brent Turner

  2. Presentation Contents: • What Is LaTeX? • History of LaTeX • LaTeX Use • Typesetting – HTML vs. LaTeX • LaTeX Syntax • Examples: document and formula • References

  3. What Is LaTeX? • TeX – typesetting standard • A TeX based document format • Used for typesetting documents • Uses tags to request elements of a document from the TeX typesetter • Not WYSIWYG

  4. TeX (the history of LaTeX) • Created by Donald E. Knuth in 1977 • Ideal for typesetting text and mathematical formulae • Mr. Knuth did not like the way publishers were formatting/typesetting his articles so he set up his own standard for authors • His website – www-cs-faculty.stanford.edu/~knuth

  5. History of LaTeX • LaTeX is pronounced “Lay-tech,” with a “k” sound, it is not pronounced “latex” as in rubber. • The “ch” originates from the Greek alphabet where X is the letter “ch” or “chi”. • tex is also the first syllable of the Greek word texnologia (technology).

  6. History of LaTeX - cont • The LaTeX program is a macro package that allows authors to use TeX easily. It is similar to a simple programming language • It is very stable and can run on almost any computer

  7. LaTeX Use • Download and install the free software. • Setup can be tricky, it is OS/machine dependant. • When using LaTeX, all document formatting is embedded within the text. • LaTeX uses control sequences (tags), which consist of a backslash (\) followed by a string of letters, possibly contained within { }, to indicate the format of the text. (see examples later)

  8. LaTeX fundamentals An author writes a LaTeX input file in a text editor and then compiles this using LaTeX. An input file has literal text along with commands to process the text. There are some conceptual similarities to a markup language such as HTML. However, a fundamental difference is that LaTeX is designed as a page layout language, unlike HMTL which is functional markup. The whole point of LaTeX is to achieve perfect typographic output, which is not the purpose of HTML.

  9. Typesetting – HTML vs. LaTeX

  10. Syntax • Using LaTeX to produce a document: \documentclass \begin{document} (The text is typed here) … \end{document} • LaTeX will automatically indent and put it in paragraph form. • To not indent a paragraph, we can use the \noindent tag at the beginning of the paragraph. • See the documentation for a complete list of tags.

  11. Tags – a short list

  12. Example:

  13. Mathematical Formula Example This example prints the definition of variance and standard deviation using LaTeX syntax.

  14. Result: Trying to do this in MSWord, or other popular WYSIWYG editor = too much work!
