Exercises 11.5 1. What is one possible pair of polar coordinates of each of the points P, Q, R, S, T, U, V in the figure? In Exercises 2-6, list four other pairs of polar coordi- nates for the given point, each with a different combination of signs (that is, r> 0, 0> 0; r > 0, 0 0; and r < 0, 0 < 0). 2 3 R E I IN P 3 S T u LO 5 2.
