Let A = [-1, 1], B = [-1, 1], C = [0,∞). Let {(x,y)ϵ A×B:x2+y2=1} – InterviewSolution

1.	Let A = [-1, 1], B = [-1, 1], C = [0,∞). Let {(x,y)ϵ A×B:x2+y2=1} and R2={(x,y)ϵ A×C:x2+y2=1}
Answer» Let A = [-1, 1], B = [-1, 1], C = $[0, \infty)$ . Let ${(x, y) ϵ A \times B : x^{2} + y^{2} = 1}$ and $R_{2} = {(x, y) ϵ A \times C : x^{2} + y^{2} = 1}$
