A problem that arose in a recent calculus class involved practical methods for finding a numerical estimate of the arc length of the curve y = x^3 from (0,0) to (2,8). So, one might ask, could one use SAGE to perform this computation, say, to 1 decimal places? (By the way, I don't thi

It sounds like a C program using MPFR (http://www.mpfr.org) would do what you want. As MPFR is built into SAGE, you might perhaps find it more convenient to invoke MPFR within SAGE. Sincerely, Greg Marks | Greg Marks
