Press
Q
to change the sign of parameter
a
.
Tap
to enter test view. In test view you can test your skill at matching an equation to the graph shown. Test view is
like equation mode in that you use the cursor keys to select and change the value of each parameter in the equation. The
goal is to try to match the graph that is shown. The functionality of test view in the Trig Explorer is almost identical to that
of test view in the Quadratic Explorer (see “Linear Explorer and Quadratic Explorer apps” on page 43).

Creating customized apps
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 an app. 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.
Like built-in apps, customized apps can be sent to another HP Prime calculator. This is explained in “Data sharing” on
page 20.
Suppose you want to create a customized app that is based on the built-in Sequence app. The app will generate the Fibonacci
sequence.
1. Press
!
and 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
E
twice.
Your new app is added to the Application Library. Note that it has the same icon as the source app—Sequence—but with the
name you gave it: Fibonacci in this example. You are now ready to use this app just as you would the built-in Sequence app.

Toolbox menus
Comprehensive menus of functions, commands, and variables are grouped together in a set of five menus known as the
Toolbox menus. You press the Toolbox key (
b
) to display these menus, labeled Math, CAS, App, User, and Catlg.
In addition to the two usual techniques for selecting a menu item—tapping it, or using the cursor keys to highlight it and then
pressing
E
—you can also type part of the name of the item and the cursor will jump to it. You can also enter the number
of the item as it appears on the menu. (The latter technique is illustrated in “CAS calculations: Some examples” on page 17.)
Math menu
This menu contains all the math functions available to you in Home view, arranged by category. Press
b
and, if necessary,
tap
. Select the appropriate category and then choose the function you want. For example, suppose you want to
determine the complex conjugate of the complex number
6+4*
