Figure 1 shows a sketch of the curves given by the polar equations
$$r = 1 \text { and } r = 2 - 2 \sin \theta$$
- Find the coordinates of the points where the curves intersect.
The region \(S\), between the curves, for which \(r < 1\) and for which \(r < 2 - 2 \sin \theta\), is shown shaded in Figure 1.
- Find, by integration, the area of the shaded region \(S\), giving your answer in the form \(a \pi + b \sqrt { } 3\), where \(a\) and \(b\) are rational numbers.
