Yes. I have toyed with adding this to non-Piecewise functions but it always ended up being easier to do it "just in time" for my course, so I haven't done so. That said, it would not be hard and would be a very good thing to do. Also, it wouldn't be hard to add that as an integration method option (with lots of warnings, "For pedagogical purposes only"), and probably should be. I feel like it *is* somewhere, but I can't remember where - maybe also in Piecewise? - kcrisman --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
