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
Demonstration
