2. A rectangle ABCD is contained in the unit circle (circle centered at the origin with radius 1). Suppose that we know the following: the point A is the origin, (0,0). the point B lies on the x-axis with a positive x-coordinate. the point C lies on the unit circle with a postive y-coordinate. Find the point D that maximizes the area of the rectangle.
