Methods of Proof - Introduction to Proof by Contraposition

Video 5 of 9 in a series presenting proof methods. This video serves as an introduction to proofs using the contrapositive, providing a description of the contrapositive of an implication and an outline to proofs using the contrapositive. The text referred to in these videos is Discrete Mathematics by Dossey, Otto, Spence and Vanden Eynden. A transition to Advanced Mathematics by Smith, Eggen and St Andre was also used as a reference while creating the notes.
