Logical equivalence (Screencast 2.2.1)

This video defines the notion of logical equivalence of statements. We show two examples of using truth tables to establish logical equivalence of statements and look at what it means for two statements NOT to be logically equivalent.

My teacher at the University of Oregon is using these videos for us to view privately for lectures in conjunction with the book. In class, it's helped free him up for better exercises and questions about homework and the material that he normally wouldn't have had. I love these videos!
