Chapter 0.1, exercise 4 (in Piazza, search on @8). In grading these assignments, I want to emphasize that we are not just looking for a "correct answer" but for a process by which you arrive at the answer. In other words, justify!
Chapter 0.2, exercise 17 (not end-of-chapter problem 17, but end-of-section problem 17). In Piazza, search on @10.
