Graphing a Recursion

An expression can be graphed as a connect type graph (G-Connect) or a plot type graph (G-Plot).

Example: To graph an+1 = 2an+1, a1 = 1

u ClassPad Operation

(1)Start up the Sequence Editor.

•If you have another application running, tap mand then H.

•If you have the Sequence application running, tap Oand then [Sequence Editor].

(2)Tap the [Recursive] tab.

(3)Specify the recursion type by tapping [Type] and then [an+1Type a1].

(4)Input the recursion expression.

•Tap the input box to the right of an+1:, and then use the procedures under “6-2 Inputting an Expression in the Sequence Application” to input the following. 2[n,an] [an]+1E

(5)Input the initial value.

1E

(6)Tap Oand then [Settings] and [View Window].

•This displays a dialog box for configuring View Window settings.
