•From app functions

Some of the functions on the App menu can be incorporated into a definition. The App menu is one of the Toolbox menus (D). The following definition incorporates the app function PredY:

F9(X)=X2+Statistics_2Var.PredY(6).

•From the Catlg menu

Some of the functions on the Catlg menu can be incorporated into a definition. The Catlg menu is one of the Toolbox menus (D). The following definition incorporates a command from that menu and an app variable: F6(X)=X2+INT(Root). The integer value of the last root calculated in the Function app is substituted for INT(Root) when this definition is evaluated.

•From other definitions

You could, for example, define F3(X)as F1(X)*F2(X).

Evaluate a dependent definition

If you have a dependent definition—that is, one defined in terms of another definition—you can combine all the definitions into one by evaluating the dependent definition.

1.Select the dependent expression.

2.Tap .

Consider the example at the right. Notice that F3(X)is defined in terms of two other functions. It is a dependent definition and can be evaluated. If you highlight F3(X)and tap , F3(X)becomes

2* X2+X+ 2 *(X2 –1).

Select or deselect a definition to explore

In the Advanced Graphing, Function, Parametric, Polar, Sequence, and Solve apps you can enter up to 10 definitions. However, only those definitions that are selected in Symbolic view will be plotted in Plot view and evaluated in Numeric view.
