The results of solve() are Sage's symbolic equations. You can get at their left and right hand sides with lhs and rhs respectively. sage: eqs = solve([x^2 - 1], x); eqs [x == -1, x == 1] sage: [eq.rhs() for eq in eqs] [-1, 1] --Mike --~--~---------~--~----~------------~-------~--~----~ 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://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
