Most of the problems have answers in the back of the book.
      Do not use online sites that give you step-by-step solutions.
      For graphs you may use the computer program of your choice,
      but do write down which program you are using.

      I have not included due dates. Try to get them in the week
      after they are covered, but before the tests dates, which we
      will set later. Please do not dump a lot of problems for me
      to grade at the last minute.
