Adding a note to an app

You can add a note to an app. Unlike general notes (created via the Note Catalog) an app note is not listed in

the Note Catalog. It can only be accessed when the app is open.

An app note remains with the app if the app is sent to another calculator.

To add a note to an app:

1. Open the app.

Press .

If a note has already been created for this app, its contents are displayed.

Tap and start writing (or editing) your note.

The format and bullet options available are the same as those in the Note Editor.

4. To exit the note screen, press any key. Your note is automatically saved.

Creating an app

The apps that come with the HP Prime calculator are built in and cannot be deleted. They are always available

(simply by pressing

). However, you can create any number of customized instances of most apps. You

can also create an instance of an app that is based on a previously customized app. Customized apps are

opened from the application library in the same way that you open a built-in app.

The advantage of creating a customized instance of an app is that you can continue to use the built-in app for

some other problem and return to the customized app at any time with all its data still in place. For example,

you could create a customized version of the Sequence app that enables you to generate and explore the

Fibonacci series. You could continue to use the built-in Sequence app to build and explore other sequences

and return, as needed, to your special version of the Sequence app when you next want to explore the

Fibonacci series. Or you could create a customized version of the Solve app—named, for example, Triangles—

in which you set up, just once, the equations for solving common problems involving right-angled triangles

(such as H = O/SIN(θ), A = H*COS(θ), O = A*TAN(θ), and so on). You could continue to use the Solve app to solve

other types of problems but use your Triangle app to solve problems involving right-angled triangles. Just

open Triangles, select which equation to use—you won’t need to re-enter them—enter the variables you

know, and then solve for the unknown variable.

Like built-in apps, customized apps can be sent to another HP Prime calculator. 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 following:

●

Linear Explorer

●

Quadratic Explorer

●

Trig Explorer
