Someone pointed out a program yesterday called PQRS. You can use it to calculate probabilities and create a small graph of the probability distribution. Very useful for teaching, I'd been looking for something like this. It's available at http://www.eco.rug.nl/medewerk/knypstra/pqrs.html I just downloaded it myself, it says that a Cauchy distribution is indeed a special case of the t-distribution.
