32 WORKING WITH NOTES & THE NOTEPAD 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. Aplet notes vs. independent notes 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). 217
