HP Prime Graphing NW280AAABA manual Fibonacci in this example

Like built-in apps, customized apps can be sent to another HP Prime calculator. This is explained in “Sharing data” on page 44. Customized apps can also be reset, deleted, and sorted just as built-in apps can (as explained earlier in this chapter).

Note that the only apps that cannot be customized are the:

•Linear Explorer

•Quadratic Explorer and

•Trig Explorer apps.

Example Suppose you want to create a customized app that is based on the built-in Sequence app. The app will enable you to generate and explore the Fibonacci series.

1.Press Iand use the cursor keys to highlight the Sequence app. Don’t open the app.

2.Tap . This enables you to create a copy of the built-in app and save it under a new name. Any

data already in the built-in app is retained, and you can return to it later by opening the Sequence app.

3.In the Name field, enter a name for your new app—say, Fibonacci—and press Etwice.

Your new app is added to the Application Library. Note that it has the same icon as the parent app—Sequence—but with the name you gave it:

Fibonacci in this example.

4.You are now ready to use this app just as you would the built-in Sequence app. Tap on the icon of your new app to open it. You will see in it all the same views and options as in the parent app.

In this example we have used the Fibonacci series as a potential topic for a customized app. To see how to create the Fibonacci series once inside the Sequence app—or an app based on the
