We don't have the Maxima function trigreduce wrapped in Sage, but you can access it like this: sage: f = cos(q1)*cos(q2) - sin(q1)*sin(q2) sage: maxima(f).trigreduce().sage() cos(q2 + q1) --Mike --~--~---------~--~----~------------~-------~--~----~ 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 -~----------~----~----~----~------~----~------~--~---
