Apps and their views
In addition to these apps, which can be used in a variety
of applications, the HP 39gII is supplied with three apps
for exploring function families: The Linear, Quadratic,
and Trig Explorers. These apps will retain their data so
you can return to them and find them as you left them, but
they are not designed to be customized and saved like
the other HP Apps.
As you use an app to explore a lesson or solve a problem,
you add data and definitions in the app's views. All of
this information is automatically saved in the app. You
can come back to the app at any time and the information
is all still there. Or you can save the app with a name you
give it and then use the original app for another problem
or purpose. See the chapter
Extending Your Aplet Library
for more information regarding customizing and saving
HP Apps.
