Defining a Graph

This chapter describes the process for graphing functions in

Func

graphing mode, but the

process is similar for each TI

-86 graphing mode. Chapters 8, 9, and 10 describe the unique

aspects of polar, parametric, and differential equation graphing modes. Chapter 6 describes
various graphing tools, many of which you can use in all graphing modes.

ᕡ Set the graphing mode (page 74).
ᕢ Define, edit, or select one or more functions in the equation editor (pages 76 and 77).
ᕣ Select the graph style for each function (page 79).
ᕤ Deselect stat plots, if necessary (page 81).
ᕥ Set the viewing window variables (page 81).
ᕦ Select the graph format settings (page 83).

Setting the Graph Mode

To display the mode screen, press - m. All default mode
settings, including

Func

graphing mode, are highlighted in the

picture to the right. The graphing modes are on the fifth line.

Func

(function graphing)

Pol

(polar graphing; Chapter 8)

Param

(parametric graphing; Chapter 9)

DifEq

(differential equation graphing; Chapter 10)

Some of these steps are not
necessary every time you
define a graph.
