Problems
Each of the problems comes with a number of experience points (XP's) you gain by doing it (mostly correctly).
The goal is to reach a minimum of 42 experience points by the end of the course.

Sage
As part of this course, we will explore the open-source free computer algebra system Sage.
If you don't have access to Sage yet, please create an account at http://cloud.sagemath.com. This free cloud service does not require you to install anything, and you can access your files and computations from any computer as long as you have internet.
Introduction to Sage
Here are the notebooks that we explored in lab:
If you are logged into your cloud account, you can play around with these files (which initially show up as read-only) by copying them to one of your personal projects (click on the light blue button with an i and select Copy...).
LaTeX and Sage
The superb package sagetex allows you to include Sage computations into your LaTeX file. Below is the example file we discussed in lab:
See http://www.sagemath.org/doc/tutorial/sagetex.html for more information on sagetex. More examples are included with the sagetex package; see, for instance, the resulting document: http://tug.ctan.org/macros/latex/contrib/sagetex/example.pdf
WZ algorithms for Sage
Following the description in the excellent book A=B by Marko Petkovsek, Herbert S. Wilf and Doron Zeilberger, I have implemented Celine's method, Gosper's algorithm and Zeilberger's algorithm in Sage, so we can play with these and prove identities:
The code requires the ore_algebra package by Manuel Kauers, Maximilian Jaroschek, and Fredrik Johansson to be installed.
(7/2020: wz.py was fixed to run with Sage 9 and ore_algebra 0.4; it may or may not run with previous versions.)
