The first exam
The first exam will be on Friday, September 9, 2005.  It will include all of Chapter 1.  You will need to bring your own paper to present your answers, and you will find a scientific calculator useful.  (Contact me if that is a problem.)  Pay particular attention to the following:
  1. Exponential models of growth and decay.  (Expect a word problem in which you will need to answer several questions.)
  2. Rates of growth of functions of various kinds, including polynomials, rational functions, logarithms, exponentials, etc.  Be able to compare the rates of growth of different functions.
  3. Solution of equations that contain the variables in exponents.
  4. The limit notation; existence of limits (or not), and computing limits.
