Suppose an arc of length s lies on the unit circle x2 + y2-1, starting at point (1. C and terminating at the point (x, y). Use a calculator to find the approximate coordinates (x, y). Round coordinates to four decimal places when appropriate. y-sina (y) (-1, 0) 00, 1) Are of length (0,-1) The unit circle x2 + y2-1 (1, 0)
