WebOct 17, 2024 · 7.1: Binary Relations. Recall that, by definition, any function f: A → B is a set of ordered pairs. More precisely, each element of f is an ordered pair (a, b), such that a ∈ A and b ∈ B. Therefore, every element of f is an element of A × B, so f is a subset of A × B. Every function from A to B is a subset of A × B. WebNov 13, 2024 · In mathematics, an equivalence relation is a binary relation that is reflexive, symmetric and transitive. The relation "is equal to" is the canonical example of an equivalence relation, where for any objects a, b, and c: a = a (reflexive property), if a = b then b = a (symmetric property), and
