Hi, In Sage 7.2.beta4:
sage: assume(x>0) sage: sin(pi*x) 0 As far as I can tell, this bug has been introduced in Sage 7.2.beta0. Maybe by ticket #20134 <http://trac.sagemath.org/ticket/20134> (upgrade to pynac-0.6.4) ? Best wishes, Eric. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
