The hp 39gs & hp 40gs provide access to Notes which can either be attached to an aplet or exist independ
ently. The notes belonging to the standard aplets are blank unless you add to them, but copies you transfer
from a computer or another calculator may have had notes added to them as instructions on how to use them.
In particular, any special aplets you download to your calculator from the internet may have instructions as a
note and/or perhaps a sketch.
Every aplet has a note attached which, by default, is blank. This note is
available via a key labeled
NOTE
(above
APLET
). Thus an instruction
to ‘press
NOTE
’ will refer to the current aplet’s Note.
In addition to this, there is a
Notepad Catalog
containing independent
notes which is available via a
NOTEPAD
, found above zero. In the
explanations below, an instruction to ‘press
NOTEPAD
’ will always refer
to the
Notepad Catalog
, not to the aplet Note. The average user will
probably not use the aplet Note.
Notes attached to aplets are explained in the chapter “Using, Copying & Creating Aplets” on page 226, so
only a brief example is given below.
The Slope Fields aplet is a special educational aplet that can be used to
introduce calculus students to the concept of fields of slopes. It has been
downloaded onto my calculator from the author’s web site the
HP
HOME view
web site (http://www.hphomeview.com) and is now
found on the
APLET
key.
This is not a standard aplet. Unless you
download this aplet yourself you will not find it
on your calculator!
When this aplet is run, the first thing visible is the
VIEWS
menu. This
menu is set up by the programmer to control the aplet
(see “Programming the hp 39gs & hp 40gs” on page 255).
