3. Press the NUM key to see a table of values for the sequence. Figure 37 shows the first six terms of each
sequence. You can explore the sequences using the direction keys. With the highlight bar in the N column, you
can also manually enter any counting number and the table will jump to that value.
4. Now that the sequence has been defined and you have checked the results, it is time to save the Aplet under
a new name. Press the APLET key and then press the SAVE menu key. Press the A...Z menu key to lock the
Alpha-shift on and enter a new name for the Aplet, as shown in Figure 38. Press the OK menu key to accept
your new name and the Aplet will show up as a new Aplet in the Library (Figure 39).
5. Use the SEND menu key to send your new Aplet wirelessly. Select the Aplet you want to share, then align the
arrows at the top of the sending and receiving calculators. Have the person receiving the Aplet press the
RECEIVE menu key when you press the SEND menu key. Both of you should choose the default option of HP39
(IrDA) by pressing the OK menu key, and the transfer will complete within a few seconds.
6. When you press the START menu key on the new Aplet, the definitions for the sequences appear. Press the
NUM key to start exploring the sequences numerically.
The advantage you get from saving an Aplet is that now you can use the underlying Aplet for some other problem and still come back to the saved Aplet
at any time. For example, you can save the Solve Aplet with multiple Physics formulas as Physics, then use the Solve Aplet to solve other equations. Your
Physics Aplet is still available - just as you left it. The Fibonacci Aplet you have just created and shared is a very simple example of a custom Aplet based
on one of the built-in HP Aplets. In fact, these custom Aplets can contain programs, notes, and sketches. Please see the HP 39gs Graphing Calculator
