This page contains information on downloading and installing free software to produce documents with the LaTeX text processing system.
Use of LaTeX in MA361 is strictly optional. However, LaTeX is a very useful skill to have in any situation where you need to communicate mathematical content.
As with most projects involving computers and software, one should expect to encounter a certain amount of frustration at the beginning of the learning curve, but from personal experience I expect that you will be satisfied with the return on your investment.
There are a lot of small pieces with LaTeX, and Miktex is like a bundle that contains everything you need to get started.
Miktex focuses on processing LaTeX files, which usually have a .tex file extension. The assumption is that you have somehow produced a .tex file, and want to process it. Miktex provides the facilities to translate raw LaTeX code into device independent (.dvi), postscript (.ps), and pdf (.pdf) files. It also has facilities for viewing .dvi files.

It's not absolutely necessary to use Texmaker or a similar product. Many people simply build the .tex files with their favorite text editor (a bit of a problem with windows, since it does not provide a sophisticated text editor). When I was first learning to use LaTeX I used a free graphical LaTeX editor called Klyx that runs on Linux, but as I gained experience I found it was faster to simply type the LaTeX code into a text editor.

The products listed on this page are free, open-source products, meaning anyone is free to download them and use them without charge. You can even obtain and modify the actual program code and sell it, subject to certain restrictions, if you choose to.
The relative merits of open source versus traditional closed source development is currently the subject of much debate (and litigation) in the computer industry today.
