Getting started
Aplets are stored in the Aplet
library. See “Aplet library” on
page 1-15 for further
information.
You can modify configuration
settings for the graphical, tabular, and symbolic views of the
aplets in the following table. See “Aplet view configuration”
on page 1-17 for further information.
In addition to these aplets, which can be used in a variety of
applications, the HP 39G/40G is supplied with two teaching
aplets: Quad Explorer and Trig Explorer. You cannot modify
configuration settings for these aplets.
A great many more teaching aplets can be found at HP’s web
site and other web sites created by educators, together with
accompanying documentation, often with student work
sheets. These can be downloaded free of charge and
transferred to the HP 39G/40G using the separately supplied
Connectivity Kit.
