Suppose that (r, 0) describes the sailing speed, r, in knots, at an angle 0 to a wind blowing at 20 knots. You have a list of all ordered pairs (r, 6) for integral angles from 0 = 0° to 8 = 180°. Describe a way to present this information so that a serious sailboat racer can visualize sailing speeds at different sailing angles to the wind.
