50PRACTICE PROBLEM
Consider an arc of length p on the unit circle x2 + y2 = 1. The starting and terminating points of the arc are (1, 0) and (x, y), respectively. With the help of a calculator, determine the approximate coordinates of the point (x, y) when p = -6.8. Round the answer to four decimal places.
