Yes, I can confirm this in the following way: sage: solve(x == sqrt(1+x), x) [x == sqrt(x + 1)] > It should be > fairly easy to solve and has a solution being the golden ratio. Yes, the above problem should be simple to solve. See for example the following equivalent way to express the above expression and the corresponding solution you seek: sage: solve(x^2 - x - 1, x) [x == -1/2*sqrt(5) + 1/2, x == 1/2*sqrt(5) + 1/2] > Unfortunately, Sage simply returns the same equation.

Then solve for each of those equivalent expressions. You never know what you'll get. -- 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
