Annotating an aplet with notes

The Note view ( NOTE) attaches a note to the current aplet. See Chapter 17, “Notes and sketches”.

Annotating an aplet with sketches

The Sketch view ( SKETCH) attaches a picture to the current aplet. See chapter 17, “Notes and sketches”.

H I N T Notes and sketches that you attach to an aplet become part of the aplet. When you transfer the aplet to another calculator, the associated note and sketch are transferred as well.

Downloading e-lessons from the web

In addition to the standard aplets that come with the calculator, you can download aplets from the world wide web. For example, Hewlett-Packard’s Calculators web site contains aplets that demonstrate certain mathematical concepts. Note that you need the Graphing Calculator Connectivity Kit in order to load aplets from a PC.

Hewlett-Packard’s Calculators web site can be found at:

Sending and receiving aplets

A convenient way to distribute or share problems in class and to turn in homework is to transmit (copy) aplets directly from one HP 39gs to another. This can take place via the infrared port or via a suitable cable. (You can use a serial cable with a 4-pin mini-USB connector, which plugs into the RS232 port on the calculator. The serial cable is available as a separate accessory.)

You can also send aplets to, and receive aplets from, a PC. This requires special software running on the PC (such as the PC Connectivity Kit). A USB cable with a 5-pin mini- USB connector is provided with the hp39gs for connecting with a PC. It plugs into the USB port on the calculator.
