Well, you know, this might be the clue I was looking for. And I suppose that this points up the idea mentioned earlier that knowledge of Python might be a prerequisite for really using sage. I wasn't aware that I could pass t to xt and yt without explicitly calling xt(t) and yt(t), and doing it your way seems to avoid the 'sage.rings.integer.Integer' object is not callable problem. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
