Chapter 6, Problem 70(choose chapter or problem)
(a) Let P be a point on the unit circle. As indicated in the following figure, rotating the point P about the origin through an angle of p radians yields a point P (on the unit circle) that is the reflection of P through the origin. Use this observation and the definition of symmetry about the origin (on page 58) to explain in complete sentences why y x P x@+y@=1 P sin1u p2 sin u and cos1u p2 cos u 1(b) Use the results in part (a) to show that(c) As examples of the results in parts (a) and (b), use acalculator to verify each of the following statements:
