The above Kuratowski definition of the ordered pair is "adequate" in that it satisfies the characteristic property that an ordered pair must satisfy, namely that . In particular, it adequately expresses 'order', in that is false unless . There are other definitions, of similar or lesser complexity, that are equally adequate:

This property is useful in the formal definition of an ordered pair, which is stated here but not explored in-depth. The currently accepted definition of an ordered pair was given by Kuratowski in 1921 (Enderton, 1977, pp. 36), though there exist several other definitions.

(In contrast, the unordered pair {a, b} equals the unordered pair {b, a}.). Ordered pairs are also called 2-tuples, or sequences of length 2; ordered pairs of scalars are also 2009-11-28 2018-04-29 Ordered Pair. more Two numbers written in a certain order. Usually written in parentheses like this: (12,5) Which can be used to show the position on a graph, where the "x" (horizontal) value is first, and the "y" (vertical) value is second. So (12,5) is 12 units along, and 5 units up. You Can Use Kuratowski's Set Definition Of Ordered Pair . This question hasn't been answered yet Ask an expert.

Cookie-policy; To contact us: mail to admin@qwerty.wiki An 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. Question: Use The Fundamental Property Of Ordered Pairs, But Not Kuratowski's Definition, To Show That If ((a, B), A) = (a, (b, A)), Then A = B. Use The Fundamental Property Of Ordered Pairs And Kuratowski's Definition To Show That A pair in which the components are ordered is basically an arrow between the components, which is sometimes called or analyzed as an interval within a larger context. Formalisations One may wish to declare ordered pairs to exist by fiat, which was done, for example, by both Bourbaki and Bill Lawvere .

Hello. I have understood the Kuratowski definition of the ordered pair and appreciate it's usefulness but have a nagging difficulty about it. Consider an ordered pair which is (a,a). according to Kuratowski definition it is defined as {{a},{a,a}} . Now consider an ordered triplet (a,a,a) it In classical Euclidean geometry (that is in synthetic geometry), vectors were introduced (during 19th century) as equivalence classes, under equipollence, of ordered pairs of points; two pairs -tuple is defined inductively using the construction of an ordered pair. In mathematics, specifically set theory, the Cartesian product of two sets A and B, denoted A×B, is the set of all ordered pairs Ordered pairs of scalars are sometimes called 2-dimensional vectors.

There are many mathematical definitions of ordered pair which have this property. The definition given here is the most common one: [math](a,b) = \{\{a\}, \{a,b\}\}[/math]. Kazimierz Kuratowski was the first person to make this definition.ru:Пара (математика)#Упорядоченная пара Answer to this is triple ordered pair. you can use Kuratowski's set definition of ordered pair This page is based on the copyrighted Wikipedia article "Ordered_pair" ; it is used under the Creative Commons Attribution-ShareAlike 3.0 Unported License.

In mathematics, an ordered pair is a collection of two objects, where one of the objects is first (the first coordinate or left projection), and the other is second (the second coordinate or right projection). Ordered pairs are also called 2-tuples, 2-dimensional vectors, or sequences of length 2. The entries of an ordered pair can be other ordered pairs, enabling the recursive definition of ordered n-tuples (ordered lists of n objects). For example, the ordered triple (a,b,c) can be defined as (a, (b,c)), i.e., as one pair nested in another.

(The notation (a, b) is also used to denote an open interval on the real number line; context should make it clear which meaning is meant. In mathematics, an ordered pair (a, b) is a pair of objects.
