If you plan to print, PDF is usually the better choice. In the case of the course assignment list generally you may only want to print the first page.
Please use a web browser that is MathML capable. The free cross-platform browsers called Firefox (version 2.0 or later) and Sea Monkey of the open source Mozilla Project are recommended. Another possibility is a plugin called MathPlayer for use with InterNet Explorer. For more information, please refer to the World Wide Web Consortium's MathML page.
