No, I meant the original f with that. SR(f) coerces (I think that's the correct word) to SymbolicRing, and this does indeed work properly; the original f isn't 'Symbolic' in that sense, but just a 'Polynomial'. With the original f, plot() calls f.plot() which doesn't take (x,0,5), but rather wants two endpoints. These now have Trac tickets, by the way (#9795 and #9794). - kcrisman -- To post to this group, send an email to [email protected] To unsubscribe from this group, send an email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
