TeX is a wonderful way to typeset Mathematics beautifully. Though the initial learning curve is steep, TeX provides full control over the produced PDFs. Here are a few sample TeX documents for various things you may use while at Syracuse University (keep in mind your content need not be the same, these samples are to demonstrate TeX, not course/syllabi material). Note for security reasons, TeX files cannot be saved to this website. If you wish to TeX these documents yourself, simply download the 'TeX' file and copy/paste it into your typesetting program of choice. It may very well be that you may be missing packages to compile some of these files. If that is the case, simply download the missing packages (they most likely can be found at this site) to your TeX folder on your personal computer.
For those only just starting in TeX, here are a number of links to help you along the way. Of course, if you are having trouble you can always ask your fellow graduate students for help or possible pre-built templates they might already have.

Introduction to Beamer
Like TeX, Beamer produces TeX'ed slides that allow navigation within the presentation. Similarly to TeX, the output is a PDF so that there is never a compatibility issue with presenting at various conferences. Below are a few links to help those getting started in Beamer.
