Direct Product (Set)
The direct product of two sets 
and 
is defined to be the set of all points 
where 
and 
. Thedirect product is denoted 
or 
and is also called the Cartesian Product, since it originatedin Descartes' 
formulation of analytic geometry. In the Cartesian view, points in the plane are specifiedby their vertical and horizontal coordinates, with points on a line being specified by just one coordinate. The mainexamples of direct products are Euclidean 3-space (
, where
are the Real Numbers), and the plane (
