Problems

Do the following problems. You do not need to turn in answers for the ones marked ``Not to turn in''. Most such problems will be those for which the textbook provides an answer in the back of the book, so you can check your work.

  1. (Not to turn in.) Do problem 7 on p. 140 of the textbook.

  2. (Not to turn in.) Do problem 34 on p. 142 of the textbook.
