Points P and Q on the unit circle are reflected images of each other, using the y-axis as a mirror. Suppose that P is described by the angle 0; what angle describes Q? In terms of o, what are the rectangular coordinates of P? Simplify the expressions cos(180 - 0) and sin(180 - 0) by finding two different ways of writing the rectangular coordinates for
