WebApr 24, 2024 · Definitions. A partial order on a set S is a relation ⪯ on S that is reflexive, anti-symmetric, and transitive. The pair (S, ⪯) is called a partially ordered set. So for all x, y, z ∈ S: x ⪯ x, the reflexive property. If x ⪯ y and y ⪯ x then x = y, the antisymmetric property. WebExample: Set A = {1,2,3,4} and set B = {5,6,7,8} are disjoint sets, because there is no common element between them. ... If set A and set B are two sets then the cartesian product of set A and set B is a set of all ordered pairs (a,b), such that a is an element of A and b is an element of B. It is denoted by A × B.

WebConsider an example of two sets, A = {2, 5, 7, 8, 9, 10, 13} and B = {1, 2, 3, 4, 5}. The Cartesian product A × B has 30 ordered pairs such as A × B = { (2, 3), (2, 5)… (10, 12)}. From this, we can obtain a subset of A × B, by introducing a relation R between the first element and the second element of the ordered pair (x, y) as flush black pirWebCartesian Product and Ordered pairs Solved Examples Example 1: To take an example, let us take P as the set of grades in a school from set Q as the sections for the grades.
