WebThe set of elements that belong to set A but not to set B is called ______ of two sets A and B Cartesian the set of all possible ordered pairs of the form (a,b) where a E A and b E B is called the _______ product of set A and set B Disjoint Two sets with no elements in common are called ____ sets 3 If one agrees that set theory is an appealing foundation of mathematics, then all mathematical objects must be defined as sets of some sort. Hence if the ordered pair is not taken as primitive, it must be defined as a set. Several set-theoretic definitions of the ordered pair are given below( see also ). Norbert Wiener proposed the first set theoretical definition of the ordered pair in 1914:

Webunion of all the sets that are members of the set to the far right and this union is deﬁned to be set A. Definition 3.4.2. If R is an equivalence relation on a set A, the set of equivalence classes of R is denoted A/R. Theorem 3.4.1 follows fairly easily from Theorem 3.3.1 in Section 3.3. Here is a proof of one part of Theorem 3.4.1. Proof. WebAn ordered pair is defined as a set of two objects together with an order associated with them. Ordered pairs are usually written in parentheses (as opposed to curly braces, which are used for writing sets). In the ordered pair the element is called the first entry or first component, and is called the second entry or second component of the pair.

WebAn ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of (x, y). The first number corresponds to the x-coordinate and the second to the y-coordinate. To graph a point, you draw a dot at the coordinates that corresponds to the ordered pair.
