Setting a mode
This example demonstrates how to change the angle measure
from the default mode, radians, to degrees for the current
aplet. The procedure is the same for changing number format
and decimal mark modes.
1. Press >6+,)7@MODES to open the HOME MODES input
form.
The cursor (highlight) is in
the first field, Angle
Measure.
2. Press
to display a

Aplets (E–lessons)
Aplets are the application environments where you explore
different classes of mathematical operations. You select the
aplet that you want to work with.
Aplets come from a variety of sources:
• Built-in the HP 39G/40G (initial purchase).
• Aplets created by saving existing aplets, which have been
modified, with specific configurations. See “Creating
new aplets based on existing aplets” on page 16-1.
• Downloaded from HP’s Calculators web site.
• Copied from another calculator.
