In this lesson, we'll build on our new concept of sets to determine when one set is a subset of another or equal to another, and learn the set operations of union, intersection, complement, difference, symmetric difference, and Cartesian product. We'll also learn the concept of cardinality of a set and how to form the power set of a set.
Basic Learning Objectives: Before our class meeting, use the Resources listed below to learn all of the following. You should be reasonably fluent with all of these tasks prior to our meeting; we will field questions on these, but they will not be retaught.
Advanced Learning Objectives: During and after our class meeting, we will work on learning the following. Fluency with these is not required prior to class.
