NOTE: I will set the threshold so that you can score at least 100% if
  you successfully complete five of the eight exercises.  If you are
  short of time, simply choose your five favorite exercises (and perhaps
  a sixth one as insurance in case you get one wrong).

1. Exercies 6.4 (a)  [ part a only ]
2. Exercise 6.7
3. Exercise 6.14  [ A related problem is cutting silicon chips from a wafer ]
4. Exercise 6.17
5. Exercise 6.22
6. Exercise 6.26
7. Exercise 6.28
8. Exercise 6.30
