LaTeX is a powerful tool for creating documents that contain a lot of mathematical symbols, equations, etc. It may seem a little strange at first, but you'll soon be proficient at making and editing LaTeX documents. Some of you may end up thinking that LaTeX expertise is the most valuable thing you got from this course!
The easiest way to get started in LaTeX is to take someone else's LaTeX document and modify it. Here is a sample document, called sample.tex, that you can begin with: sample.tex. All LaTeX document files should end with the suffix ".tex".
There are many good sources on the Web for learning about LaTeX; here is a link to an old but good one. A Google search for "latex tutorial" will turn up many more.
