Extending aplets
Aplets are the application environments where you
explore different classes of mathematical operations.
You can extend the capability of the HP 40gs in the
following ways:
• Create new aplets, based on existing aplets, with
specific configurations such as angle measure,
graphical or tabular settings, and annotations.
• Transmit aplets between HP 40gs calculators via a
serial or USB cable.
• Download e-lessons (teaching aplets) from
Hewlett-Packard’s Calculator web site.
• Program new aplets. See chapter 21,
“Programming”, for further details.
Creating new aplets based on existing aplets
You can create a new aplet based on an existing aplet.
To create a new aplet, save an existing aplet under a new
name, then modify the aplet to add the configurations
and the functionality that you want.
Information that defines an aplet is saved automatically
as it is entered into the calculator.
To keep as much memory available for storage as
possible, delete any aplets you no longer need.
Example This example demonstrates how to create a new aplet by
saving a copy of the built-in Solve aplet. The new aplet is
saved under the name “TRIANGLES” and contains the
formulas commonly used in calculations involving
right-angled triangles.
