Assignment #6--Due Thursday, March 10

Reading: Sections 16, 17, 18, 19

Notes: For 16.7(f), use Bernoulli's inequality (exercise 10.22) as suggested by the hint in the back. While the inequality is not difficult to prove, you can take it for granted here. For 17.15(c), don't hesitate to first try 17.15(a) as a "warm up" for this exercise, even though part (a) is not assigned. Going through that exercise and considering the hint will be helpful.

Notes: Exercise 20.17 will be slightly easier once you've gone through Section 21 thoroughly. On your own (meaning you do not need to address this in your write up), note the connection between this problem and Exercise 21.5. Also, on your own, note the connection between Exercise 21.13 and Exercise 20.16.
