The three specialized Solvers—outlined in the following table—are designed to help you solve problems of a specific type.

Table 2-2 HP Solver apps

Three apps are specifically designed to help you explore the relationships between the values of the parameters in a function

and the shape of the graph of the function. See the following table.

Table 2-3 HP Explorer apps

Data persistence

When you work with an app, you enter data of one sort or another, such as definitions of functions, window settings, and

preferences. The app records all this data and automatically saves it for you. If you leave the app and come back to it later,

all that data is still there. In fact, you can save an instance of the app with a new name and keep the original version for

another purpose. The new version, under the new name, contains all the data from the source app. (This is explained in

“Creating customized apps” on page 46.)

If you don’t want to retain the data stored with an app when you next open the app, you can reset the app to its default values

and settings. With the Application Library displayed (!), use the cursor keys to highlight the app you want to reset, and

then tap . Confirm your intention to reset the app by tapping or pressing

Data sharing

Using the supplied USB cable, you can send an app from one HP Prime calculator to another. It can be a built-in app or one

you’ve customized. In fact, you can share with other HP Prime users many of the objects you create using your HP Prime

calculator, such as programs, notes, lists, and matrices.
