Sage calls out to Maxima for all of the simplify_foo() functions. It wouldn't be too hard to tell Sage about the identity and make the substitution yourself (I was going to attempt it), but doing so is dependent on having some notion of "simpler" since you don't want it to return a more complicated expression. If there isn't one, I will probably try to think up a crazy heuristic. -- 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 URL: http://www.sagemath.org
