Hewlett-Packard Company 16399 West Bernardo Drive MS 8-600 San Diego, CA 92127-1899 USA Printing History Edition 1 April 2006 Preface You have in your hands a compact symbolic and numerical computer that will facilitate calculation and mathematical analysis of problems in a variety of disciplines, from elementary mathematics to advanced engineering and science subjects. [. . . ] Move the cursor to one of the corners of the box (using the arrow keys), and press @)ZOOM @BOXZ. Using the arrow keys once more, move the cursor to the opposite corner of the desired zoom box. The cursor will trace the zoom box in the screen. When desired zoom box is selected, press @ZOOM. The calculator will zoom in the contents of the zoom box that you selected to fill the entire screen. If you now press @ZOUT, the calculator will zoom out of the current box using the H- and V-Factors, which may not recover the graph view from which you started the zoom box operation. ZDFLT, ZAUTO Pressing @ZDFLT re-draws the current plot using the default x- and y-ranges, i. e. , 6. 5 to 6. 5 in x, and 3. 1 to 3. 1 in y. The command @ZAUTO, on the other hand, creates a zoom window using the current independent variable (x) range, but adjusting the dependent variable (y) range to fit the curve (as when you use the function @AUTO in the PLOT WINDOW input form (, , , simultaneously in RPN mode). HZIN, HZOUT, VZIN and VZOUT These functions zoom in and out the graphics screen in the horizontal or vertical direction according to the current H- and V-Factors. CNTR Zooms in with the center of the zoom window in the current cursor location. The zooming factors used are the current H- and V-Factors. ZDECI Zooms the graph so as to round off the limits of the x-interval to a decimal value. ZINTG Zooms the graph so that the pixel units become user-define units. For example, the minimum PICT window has 131 pixels. When you use ZINTG, with the Page 12-48 cursor at the center of the screen, the window gets zoomed so that the x-axis extends from 64. 5 to 65. 5. ZSQR Zooms the graph so that the plotting scale is maintained at 1:1 by adjusting the x scale, keeping the y scale fixed, if the window is wider than taller. This forces a proportional zooming. ZTRIG Zooms the graph so that the x scale incorporates a range from about 3 to +3, the preferred range for trigonometric functions. Note: None of these functions are programmable. They are only useful in an interactive way. Do not confuse the command @ZFACT in the ZOOM menu with the function ZFACTOR, which is used for gas dynamic and chemistry applications (see Chapter 3). The SYMBOLIC menu and graphs The SYMBOLIC menu is activated by pressing the P key (fourth key from the left in fourth row from the top of the keyboard). This menu provides a list of menus related to the Computer Algebraic System or CAS, these are: All but one of these menus are available directly in the keyboard by pressing the appropriate keystroke combination as follows. The Chapter of the user manual where the menus are described is also listed: ALGEBRA. . , (the 4 key) , , (the 1 key) , , (the 4 key) Ch. EXP&LN. . , , (the 7 key) , (the 8 key) , , (the 8 key) Ch. 5 The SYMB/GRAPH menu The GRAPH sub-menu within the SYMB menu includes the following functions: DEFINE: same as the keystroke sequence , , (the 2 key) GROBADD: pastes two GROBs first over the second (See Chapter 22) PLOT(function): plots a function, similar to , , PLOTADD(function): adds this function to the list of functions to plot, similar to , , Plot setup. . : same as , , SIGNTAB(function): sign table of given function showing intervals of positive and negative variation, zero points and infinite asymptotes TABVAL: table of values for a function TABVAR: variation table of a function Examples of some of these functions are provided next. PLOT(X^2-1) is similar to , , with EQ: X^2 -1. Using @ERASE @DRAW produces the plot: PLOTADD(X^2-X) is similar to , , but adding this function to EQ: X^2 -1. Using @ERASE @DRAW produces the plot: Page 12-50 TABVAL(X^2-1, {1, 3}) produces a list of {min max} values of the function in the interval {1, 3}, while SIGNTAB(X^2-1) shows the sign of the function in the interval (-, +), with f(x) > 0 in (-, -1), f(x) <0, in (-1, 1), and f(x) > 0 in (1, + ). TABVAR(LN(X)/X) produces the following table of variation: A detailed interpretation of the table of variation is easier to follow in RPN mode: The output is in a graphical format, showing the original function, F(X), the derivative F'(X) right after derivation and after simplification, and finally a table of variation. The table consists of two rows, labeled in the right-hand side. [. . . ] HP shall not be liable for technical or editorial errors or omissions contained herein.
