Homework 06

Read: up through the end of Section 4.1. The reading in at the start of Chapter 4 is dense, so please take your time and make sure to write down questions that arise.

Turn in: 3.72, 3.73, 3.75, 4.3, 4.4

• For 3.72, you’ll probably want to separately show $LHS \subseteq RHS$ and $RHS \subseteq LHS$ (like earlier problems). Theorem 3.71 is helpful, and there is a hint in the book.

Extra practice: 3.71, 3.74, 3.76
