Find the local extreme values of the function f(x, y) = xy - x2 - y2 - 3x - 3y + 12

Use the function nest to evaluate p(x) = 1 + x + · · · + x50 at x = 1.00001. (use the matlab ones command to save typing.) find the error of the computation by comparing with the equivalent expression q(x) = (x51 − 1)/(x − 1).
