WebAug 26, 2024 · Types of Relations. Mathematics Computer Engineering MCA. The Empty Relation between sets X and Y, or on E, is the empty set ∅. The Full Relation between sets X and Y is the set X × Y. The Identity Relation on set X is the set { (x, x) x ∈ X } The Inverse Relation R' of a relation R is defined as − R' = { (b, a) (a, b) ∈ R } WebAug 1, 2024 · It is transitive, since - for every $a, b, c$ such that $ (a, b)$ and $ (b, c)$ are in the empty relation - we have $ (a, c)$ is in the empty relation; this is because there are no such $a, b, c$ at all, so transitivity holds vacuously. Admin about 7 years @Gabu It's vacuously true. You should Google that phrase or search it on here.
