  • Page 7: Getting Started

    This quick start guide covers basic tasks, such as entering and editing expressions, plotting graphs, and making tables of values. This guide also serves as an introduction to HP Apps. Finally, advanced topics, like working with lists or matrices, are also intro- duced.
  • Page 8 Installing the Batteries Please install the batteries according to the following procedure: Turn off the calculator. Slide up the battery compartment cover. Insert 4 new AAA (LR03) batteries into the compartment. Make sure each battery is inserted in the indicated direction. The calculator takes 4 AAA (LR03) batteries as a main power source.
  • Page 9 The Home View Press the On key or Home to access the Home view. The HP 39gII Home view is divided into four parts, from top to bottom. There is a Header at the top, with the name of the HP App you're currently using and whether you are in degree (DEG) or radian (RAD) mode. Next comes the History of calculations.
  • Page 10 Entering and Editing Expressions To calculate , enter the expression then press Enter. The HP 39gII displays the results with -- - 12 digits of accuracy. Now press the Up cursor key twice to highlight the expression you entered. Note that two additional menu labels are now displayed: COPY and SHOW.
  • Page 11 At any time, you can press SHIFT Views (Help) to get help on the functionality in your current view. Once in the Help system, you can browse the entire list of topics and return to the current HP 39gII view at any time.
  • Page 12 Understanding the Software Menu Keys The bottom of the display contains a menu of up to six items. Use the F1-F6 menu keys to access the menu items. Choose Boxes To change the value in a Choose Box, press the CHOOS menu key, and a list of options appears.

  • Page 13: Hp Apps And App Views

    HP Apps Much of the functionality of the HP 39gII is partitioned into packages called HP Apps. The HP 39gII comes with 15 HP Apps; nine dedi- cated to mathematical topics or tasks, three specialized Solvers, and three function Explorers. These apps are listed in the tables below.
  • Page 14 These three views are supported by a set of three keys, located near the top left of the HP 39gII keyboard. These keys are Symb, Plot, and Num. Each of these three views has an additional setup view, accessed by pressing the SHIFT of the view's key.
  • Page 15 Pressing Home always takes you to the calculator history, which is not part of any App, and thus not saved with any App. The table below summarizes the purpose of each of the six main views of HP Apps. The Function App is used to illustrate the views in the table.
  • Page 16 The purpose of the Numeric Setup is to determine the appearance of the Numeric view and the type of table provided. This view is not used by the Solve app, nor is it used by the Solvers and Explorers. These latter apps have their Numeric views pre-defined by their scope. HP Apps and App Views...
  • Page 17 One note is in order concerning the Plot view. The HP 39gII gives you three options for graphing. By default, the HP 39gII uses the Adaptive method, an advanced method that gives very accurate results. You can choose the more traditional method, called Fixed-Step Segments, which samples x- values, computes their corresponding y-values, and then plots and connects the points.

  • Page 19: Hp App Summaries

    The Function App lets you define up to ten functions in x, view their graphs, create tables of values, and find intersections, roots, and extrema. The Function App is the default HP App when the HP 39gII is shipped from the factory. Table 4 summarizes the capabilities of this App.
