What motivated my question was the following problem. I have a polynomial f(x,y) with algebbraic coeffcients. If i fix a value for x, the roots of f as a polynomial in y are algebraic numbers. By the implicit function theorem, around each pair (x,y) i have a function, and i need its taylor expansion. That means i need to take the derivatives of this function using implicit derivation. That's why i wanted to move algebraic numbers from a polynomial ring to the symbolic ring and back. -- To post to this group, send an email to [email protected] To unsubscribe from this group, send an email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
