Dear Robert, I wrote a SAGE worksheet for my freshman calculus class last semester implementing the Newton-Raphson algorithm for finding roots of functions to arbitrary precision. You'll find it unduly didactic, I'm afraid, but a few of the cells toward the end might be the sort of thing you're looking for. The worksheet can be found as a text file at:
