Absolutely, definitely a special function. The main point I wanted to make, though, is that Maxima can't even do integrate(abs(sin(t)), t, 0, pi). It can't deal with absolute values in definite integrals ever. So the discussion in this thread and the parallel thread is a bit moot. :) Mark --~--~---------~--~----~------------~-------~--~----~ 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 -~----------~----~----~----~------~----~------~--~---
