CHAPTER OBJECTIVES:
This chapter shows you how to use your graphic display calculator
(GDC) to solve the different types of problems that you will meet in your
course. You should not work through the whole of the chapter – it is simply
here for reference purposes. When you are working on problems in the
mathematical chapters, you can refer to this chapter for extra help with
your GDC if you need it.
