LaTeX help

To use the LaTeX files dowload the one that you want to see, and "definitions.tex". Save them in the same directory.

Do not change the name of "definitions.tex" because it is invoked with this name by the other files.

Most likely you can dowload a file using a selection on the right button on your mouse, the one similar to "Save link as ..." or "Save link target as ...". Place the mouse over the link whose content you want to save.

For how to use LaTeX, you can read the instructions under the Introduction to Computing Resources link on my home page.
(You can also see a better written course by Harold P. Boas at TAMU.)
Go to LaTeX. On the second part of Introduction you can find instructions on how to process/view/print a LaTex file.
Apply these only to the main files, not the "definitions.tex".
To make changes use any "plain" text editor, i.e. one that does not insert any extra information in the file (as formating, fonts, etc.).
I prefer to use emacs, available for all major operating systems. You can find a description under EMACS in the same location.
There are also editors specialized for LaTeX.

Please come to see me for more details.
