Sample
1. Find A × B, A × A and B × A
(i) A = {2, −2, 3} and B = {1, −4}
A × B = {2, −2, 3} × {1, −4}
= {(2, 1), (2, −4), (−2, 1), (−2, −4), (3, 1), (3, −4)}
A × A = {2, −2,3} × {2, −2, 3}
= {(2, 2), (2, −2), (2, 3), (−2, 2), (−2, −2), (−2, 3), (3, 2), (3, −2), (3, 3)}
B × A = {1, −4} × {2, −2,3}
= {(1, 2), (1, −2), (1, 3), (−4, 2), (−4, −2), (−4, 3)}
2. If A = {5, 6}, B = {4, 5, 6}, C = {5, 6, 7}, show that A × A = (B × B) ∩ (C × C).
A × A = (B × B) ∩ (C × C)
LHS: A × A = {5,6} × {5,6}
= {(5, 5), (5, 6), (6, 5), (6, 6)} ……….(1)
RHS:
B × B = {4,5,6} × {4,5,6}
= {(4,4), (4,5), (4,6), (5,4), (5, 5),
(5, 6), (6,4), (6, 5), (6, 6)}
C × C = {5,6,7} × {5,6,7} = {(5, 5), (5, 6), (5,7), (6, 5), (6, 6), (6,7), (7,5), (7,6), (7,7)}
(B × B) ∩ (C × C) = {(5, 5), (5, 6), (6, 5), (6, 6)}……….(2)
From (1) and (2), A × A = (B × B) ∩ (C × C)
3. A × (B − C) = (A × B) − (A × C)
LHS: B − C = {2,3,5,7} − {2} = {3,5,7}
A × (B − C) = {1,2,3,4,5,6,7} × {3,5,7}
= {(1, 3), (1, 5), (1, 7), (2, 3), (2, 5), (2, 7), (3, 3), (3, 5), (3, 7), (4, 3), (4, 5), (4, 7),
(5, 3), (5, 5), (5, 7), (6, 3), (6, 5), (6, 7), (7, 3), (7, 5), (7, 7)}…………(1)
RHS: A × B = {1,2,3,4,5,6,7} × {2,3,5,7}
= {(1,2), (1,3), (1,5), (1,7), (2,2), (2,3), (2,5), (2,7), (3,2), (3,3), (3,5), (3,7), (4,2), (4,3),
(4,5), (4,7), (5,2), (5,3), (5,5), (5,7), (6,2), (6,3), (6,5), (6,7), (7,2), (7,3), (7,5), (7,7)}
A × C = {1,2,3,4,5,6,7} × {2} = {(1,2), (2,2), (3,2), (4,2), (5,2), (6,2), (7,2)}
(A × B) − (A × C)
= {(1,2), (1,3), (1,5), (1,7), (2,2), (2,3), (2,5), (2,7), (3,2), (3,3), (3,5), (3,7), (4,2), (4,3),
(4,5), (4,7), (5,2), (5,3), (5,5), (5,7), (6,2), (6,3), (6,5), (6,7), (7,2), (7,3), (7,5), (7,7)}
− {(1,2), (2,2), (3,2), (4,2), (5,2), (6,2), (7,2)}
= {(1, 3), (1, 5), (1, 7), (2, 3), (2, 5), (2, 7), (3, 3), (3, 5), (3, 7), (4, 3), (4, 5), (4, 7),
(5, 3), (5, 5), (5, 7), (6, 3), (6, 5), (6, 7), (7, 3), (7, 5), (7, 7)}…………(2)
From (1) and (2)
A × (B − C) = (A × B) − (A × C)
