I wonder if there is something wrong with the interval cosine calculation? cos seems to loop forever on [-1 .. +1]. Try this:
sage: x = RealInterval(-1.1,1.1) sage: x.cos() [0.453596121425577307 .. 1.00000000000000000] sage: x = RealInterval(-1.0,1.0) sage: x.cos() --------------------------------------------------------------------------- <type 'exceptions.KeyboardInterrupt'> Traceback (most recent call last) /files/home/nholtz/<ipython console> in <module>() --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://sage.math.washington.edu/sage/ and http://sage.scipy.org/sage/ -~----------~----~----~----~------~----~------~--~---
