WebA relation is the collection of ordered pairs. Let us consider two sets A and B. Then the set of all ordered pairs of the form (x, y) where x ∈ A and y ∈ B is called the cartesian product of A and B, which is denoted by A x B. Any subset of this cartesian product A x B is a relation. Then what is an inverse relation of a relation?
