EXAMPLES

(0;4)(0;6)

A*B=(2;4)(2;6)

(4;4) (4;6)

CARTESIAN PRODUCT FORMS

There are several ways to represent the Cartesian product, I will explain several ways:Cartesian productCartesian diagramsagittal diagramTree DiagramCrosstab

So I show better

(X;Y)

Second component

First component

Cartesian diagram

This is one of the simplest there. You just have to locate ordered pairs in the Cartesian plane

Demonstration

Sagittal diagram

This is also a very simple way to represent the ordered pairs is when the set is represented in geometric and it is distinguished by the ordered pairs

Demonstration

Crosstab

• En este gráfico se representan los pares ordenados en cuadro en el que los primeros dígitos van hacia abajo y los segundos van abajo
