  • Page 14 Before we continue, let's look at the default window settings. Press SHIFT followed by PLOT to open the Function Plot Setup, as shown in Figure 17. The HP 39gs has 131 pixel columns, allowing the cursor to make 130 steps from one vertical edge of the display to the other. The default setting for the horizontal range (XRNG) is [-6.5, 6.5], a distance of 13 units.
  • Page 15 The HP 39gs uses the current cursor location for tasks such as finding roots, intersections, and slope at a point. To find the best numerical approximation to the root, press the MENU key to restore the menu, press the FCN menu key to see the list of options, and select the ROOT command (Figure 20). Press the OK menu key.
  • Page 16 Press the Menu key to restore the menu and explore some of the other options in the Function Plot view. Refer to the HP 39gs Graphing Calculator User’s Guide on the product CD for more details. Figure 23 Function Numeric View The Function Numeric view provides a table of values for all active functions, as well as the tools needed to explore the table of values.
  • Page 17 Remember that F1(X) has a root near x=3.5. You can use the DOWN cursor key to scroll to x=3.5, but there is an easier way to get to any x-value you wish. Simply move the highlight bar to any cell in the x- column and type in the value you wish to see.
  • Page 18 39gs will supply x-values and function values in a table defined by the Function Numeric Setup view. The other option is Build Your Own. With this option, the HP 39gs presents a blank table. The user enters x- values of his/her choosing, and the calculator records those x-values and supplies the corresponding function values.
  • Page 19 Delete restores the default value for any field, whether the value is numeric or an option from a list. Highlight the NUMSTART field and press DEL to see the default NUMSTART value of zero restored, as shown in Figure 31. Pressing SHIFT followed by DEL (CLEAR) restores all default values in a menu. Figure 31 Press SHIFT followed by DEL (CLEAR) to see all fields returned to their default values, as shown in Figure 32.
  • Page 20: Aplets

    The key to working with HP Aplets is to understand that they were designed to have a similar structure. That structure is illustrated by a set of six keys, located in two rows of three keys each near the top left of the HP 39gs keyboard. The keys in the first row are SYMB, PLOT, and NUM; the keys in the sec- ond row are HOME, APLET, and VIEWS.
