Maple7 is available for students, and installation instructions have been posted on the department's software web page.

You can learn a lot about Maple by reading its help... Learning Maple is not a requirement for the class, and you can obtain maximum scores and achieve complete understanding of the material without ever using this software. Such type of knowledge may ease a bit your life in Math 23, or may come handy with other occasions during your study years. I encourage you to get familiar with Maple.

Here is the link to a comprehensive introduction to Maple.

Finally, below are some graphs that I have obtained, using Maple (or Mathematica), when I prepared the lectures for our class. Feel free to cut-and-paste any Maple command contained in the files, and use them to start learning how to work with Maple.
