Figure 21 displays the graphs of r = sin 2θ in r versus θ rectangular coordinates and in polar coordinates, where it is a “rose with four petals.” Identify:

(a) The points in (B) corresponding to points A–I in (A).
(b) The parts of the curve in (B) corresponding to the angle intervals [0, π/2], [π/2, π], [π, 3π/2], and [3π/2 , 2π].
