WebMay 8, 2024 · Definition. The definition of a set does not take any account of the order in which the elements are listed. That is, { a, b } = { b, a }, and the elements a and b have the same status - neither is distinguished above the other as being more "important". The concept of an ordered pair can be formalized by the definition:

WebDefinition: Relation A relation from a set A to a set B is a subset of A × B. Hence, a relation R consists of ordered pairs (a, b), where a ∈ A and b ∈ B. If (a, b) ∈ R, we say that is related … WebAn ordered pair is a pair of objects in which the order of the objects is significant and is used to distinguish the pair. An example is the ordered pair (a,b) which is notably different than the pair (b,a) unless the values of each variable are equivalent. Coordinates on a graph are represented by an ordered pair, x and y.
WebThe set T is defined as T = { (i, j) i, j ∈ Natural Numbers }, which means it contains all ordered pairs (i, j) where i and j are natural numbers. To show that T is countable, we need to show that there exists a one-to-one correspondence between T and the set of natural numbers. One possible way to do this is to use a diagonalization argument. WebSep 5, 2024 · We say that a set A is a subset of a set B if every element of A is also an element of B, and write A ⊂ B or B ⊃ A. Two sets are equal if they contain the same elements. If A and B are equal, we write A = B. The following result is straightforward and very convenient for proving equality between sets. Theorem 1.1.1
