The following exercises are a mixture of problems primarily from the topics covered Chapter 2. One of the objectives of these
exercises is to be able to correctly identify which topics and tools are needed for each problem. While the emphasis is on
material covered in Chapter 2, some problems covering Chapter 1 material are also included. All of the material covered in
this chapter is fair game, except for optional topics, which are not included in these exercises.
