Homework 3

Due Friday, September 28

The problem set is due at the beginning of class on Friday. Remember that a full answer to a True/False exercise is not merely a T or F, but must include a detailed explanation of the reason, e.g., a proof, or a counterexample, or a reference to a result in the text, etc.
