The solutions (x, y) of the equation x2 + 16y2 = 16 form an ellipse as pictured below. Consider the point P as pictured, with x-coordinate 2. (a) Let h be a small non-zero number and form the point Q with x-coordinate 2+h, as pictured. The slope of the secant line through PQ, denoted s(h), is given by the formul
