Q.51 Fort E R, let [t] denote the greatest integer less than or equal to t. Let D {(xy) e R2 :x2 + y2 < 4}. Let f: D - R and g: D R be defined by f(0,0) = g(0, 0) = 0 and x*y2 SCx.y)= [x +ylp4yi gxy) = "+y for (x, y) # (0,0). Let E be the set of points of D at which both f and g are discontinuous. The number of elements in the set E is
