The resultant works if you define your polynomial ring over QQ: sage: WW.<x,y> = QQ[] sage: f = x sage: g = x^10 + y sage: f.resultant(g) y See here for a patch: http://trac.sagemath.org/sage_trac/ticket/8173 Cheers, Burcin -- 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
