There are of course several trac tickets related to this, so this is not a bug report (for Sage or for Maxima), but I had to laugh when this came up today in preparing for class - enjoy!
TypeError: Computation failed since Maxima requested additional constraints (try the command 'assume(sin(t)^2+cos(t)^2>0)' before integral or limit evaluation, for example): Is sin(t)^2+cos(t)^2 positive or zero? - kcrisman --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
