WebDefining an Ordered Pair. Any point on the Cartesian or the coordinate plane is written as a combination of two values. For example, the point (x, y) when represented on the coordinate plane describes the distance of the point in relation to the origin. So this point (x, y) is called an ordered pair. The point with the coordinates (x, y) is ... 在数学中，有序对是两个对象的搜集，使得可以区分出其中一个是“第一个元素”而另一个是“第二个元素”（第一个元素和第二个元素也叫做左投影和右投影）。带有第一个元素a和第二个元素b的有序对通常写为(a, b)。 符号(a, b)也表示在实数轴上的开区间；在有歧义的场合可使用符号 See more 设(a1, b1)和(a2, b2)是两个有序对。则有序对的特征或定义性质为： $${\displaystyle (a_{1},b_{1})=(a_{2},b_{2})\leftrightarrow (a_{1}=a_{2}\land b_{1}=b_{2})}$$ 有序对可以有其他有 … See more 诺伯特·维纳在1914年提议了有序对的第一个集合论定义： $${\displaystyle (x,y)\equiv _{def}\{\{\{x\},\emptyset \},\{\{y\}\}\}}$$ 他注意到这个定义将 … See more
