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, it is important to be able to identify a basic relationship between sets. This is the idea of a subset. We also introduce a way of obtaining a new set from existing sets by constructing the Cartesian product of the sets.
