Homework 19

Read: Continue with Chapter 6 up through end of Section 6.1.1.

Turn in: 6.17, 6.20, 6.21, 6.22, 6.23, 6.24

• 6.17 should follow fairly quickly from 6.16 using the ideas in the paragraph before 6.17.
• Pease read Theorem 6.19 carefully—it is very important!

Extra practice: 6.16, 6.18, 6.19

• For 6.16, most of the work has been done; you just need to connect things. (Look back at 6.8 and 6.14.)
• 6.19 should follow fairly quickly from 6.17 and 6.18.
