If A = {1, 2, 3}, B = {1, 2}, find A $ \times $ B. Find the formula for the following relations (if any). \[\] $R_1$ = {(1, 1), (2, 2)}

1 Answer

$R_1$ consists of all those ordered pairs of A $ \times $ B whose first coordinates are equal to second coordinates. Hence the formula for $R_1$ is ‘is equal to’.
