In the above Sage session, you declared two symbolic expressions. So it is possible to use methods defined on symbolic expressions other than simplify(). In the present case, you want to use the simplify_radical() method to simplify radicals: sage: E = sqrt(2)*sqrt(3) - sqrt(6); E sqrt(2)*sqrt(3) - sqrt(6) sage: type(E) <type 'sage.symbolic.expression.Expression'> sage: E.simplify_radical() 0 > I try with the command simplify() but it doesn't do anything. For more methods defined on symbolic expressions, do sage: E. and press the Tab key. That should allow you to view a list of methods you could use on the symbolic expression E. -- Regards Minh Van Nguyen -- 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
