I found the presentation very nice, and one of the options I thought of was making a Sage worksheet "translation" of your existing pages. I understand that you may not have time to do such a thing, but would you be opposed if we did, as we had time and/or need? Would you consider posting links to such worksheets if they became available? As it was, I combined information from several sources to make my lectures, but ended up with a nice "interact" (like a Mathematica Manipulate demonstration) for Sage. You can see screenshots here: http://wiki.sagemath.org/interact/calculus#Gaussian.28Legendre.29quadrature You might find it interesting to see other "interacts" posted at the above site as well. These are snippets of code that work in the Sage notebook, an online interface that students can access from anywhere. I find them very effective for classroom demonstrations. We do not have Mathematica here at Iowa State U. (at least not readily available to the students), but every student has access to my interact on the class sage server, or can paste the code into the public sage server at http://www.sagenb.org.
