var('x y') soln = solve(y == x^3 -2, x) print soln print soln[1].right_hand_side() Sage's answer : [ x == 1/2*(I*sqrt(3) - 1)*(y + 2)^(1/3), x == 1/2*(-I*sqrt(3) - 1)*(y + 2)^(1/3), x == (y + 2)^(1/3) ] 1/2*(-I*sqrt(3) - 1)*(y + 2)^(1/3) Have a good afternoon Laurent --~--~---------~--~----~------------~-------~--~----~ 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 URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
