WebThe set of all a \in A such that aRb for at least one b \in B is called the domain of the binary relation R. The set of all b \in B such that aRb for at least one a \in A is called the codomain of the binary relation R. Representation of Binary Relations. There are many ways to specify and represent binary relations. Some of which are as follows: WebA binary relation describes a relationship between the elements of 2 sets. If A and B are sets, then a binary relation R from A to B is a subset of the Cartesian product of A and B (A x B). Example: Let A = {1, 2, 3} and B = {4, 5, 6}. Let R be a binary relation from A to B as follows: given any (x, y) A x B, (x, y) R y/x Z cshbttf-stc-d8-20
