6-a The polar coordinates are

6-b The polar coordinates are

16. rcos(q )= 1 is the vertical line x = 1

24 r = 4 tan(q )sec(q )

26 r^{2} = sec(2q
)

28-a Because its center is not at the origin the cartesian equation (x-2)^{2} + (y-3)^{2} = 25 is preferable.

28-b The two equations, r = 4 and x^{2} + y^{2} = 16 are about equal in complexity.
