The PLOT view is used to display the function as a graph... The key gives access to a number of other useful tools allowing further analysis of the function. Although these views are superficially different in other aplets, the basic idea is usually similar. Having said that aplets are best thought of as "working environments", it is equally true that aplets are essentially programs, with the standard ones simply being built into the calculator. This is a programmable calculator, having its own programming language and able to perform quite sophisticated tasks. Unless you particularly want to learn about the programming language, there is no reason why you should worry about it. The standard aplets will cover all of your normal requirements in mathematics. However one of the great strengths of the hp 39g+ is its ability to "download" additional aplets from other calculators, from a PC or Mac and from the Internet. See page 200. A cable and software were provided with your hp 39g+ which you can use to connect your PC or Mac to your calculator and then download aplets from the computer to the calculator or to save your work to the computer. If you have an hp 38g, hp 39g or hp 40g then you need to buy the cable separately. If you are using an hp 39g+ then the cable connects to the USB port on your computer. If you are using an hp 39g or an hp 40g then you will need to purchase the cable and download the software from Hewlett-Packard's website. More information on this can be found on pages 200 - 226. Calculator Tip Search on the web using the key word "hp 39g" and you will find a variety of sites which contain information and aplets. 23
