In this question we prove that certain sets are not convex. For each of the following sets, give the coordinates of two points where P and Q are in the set, but the line from P to @ goes outside the set. For example, if the points are (1, 2) and (3, 4), enter in the format (1,2), (3,4) (a) R = (x,y) : x2 + y2 2 1, y 6} n (x,y) :32
