Chapter 6 More on Sets
Objectives
Recognize whether a set is a subset of another set.
List the elements of a Cartesian product.
Recognize whether an element is in a Cartesian product.
Rewrite an image as a Cartesian product.
Convert a Cartesian product into an image.
Now that we have defined sets, we study a basic relationship between sets: the idea of a subset. We also show how to build a new set from existing sets by using the Cartesian product of the sets.
