0-1-1 Getting Acquainted uGraphs As a general rule, graph operations are shown on facing pages, with actual graph examples on the right hand page. You can produce the same graph on your calculator by performing the steps under the Procedure above the graph. Look for the type of graph you want on the right hand page, and then go to the page indicated for that graph. The steps under "Procedure" always use initial RESET settings. 5-1-1 Sample Graphs 5-1 Sample Graphs k How to drawa simple graph(1) Description To draw a graph, simply input the applicable function. Set Up 1. From the Main Menu, enter the GRAPH Mode. Execution 2. Input the function you want to graph. Here you would use the V-Window to specify the range and other parameters of the graph. See 5-2-1. 3. Draw the graph. 20050301 5-1-2 Sample Graphs Example To graph y = 3x2 Procedure 1 m GRAPH 2 dvxw 3 6(DRAW) (or w) Result Screen # Pressing A while a graph is on the display will return to the screen in step 2. 20050301 The step numbers in the "Set Up" and "Execution" sections on the left hand page correspond to the "Procedure" step numbers on the right hand page. Example: Left hand page 3. Draw the graph. Right hand page 3 5(DRAW)(or w) uCommand List The PRGM Mode Command List (page 8-7) provides a graphic flowchart of the various function key menus and shows how to maneuver to the menu of commands you need. Example: The following operation displays Xfct: [VARS]-[FACT]-[Xfct] uPage Contents Three-part page numbers are centered at the top of each page. The page number "1-2-3", for example, indicates Chapter 1, Section 2, page 3. 1-2-2 1-2-2 Display Display Icon Mode Name S • SHT (Spreadsheet) GRAPH DYNA (Dynamic Graph) TABLE RECUR (Recursion) CONICS Description Use this mode to perform spreadsheet calculations. Each file contains a 26-column ⋅ 999-line spreadsheet. In addition to the calculator's built-in commands and S • SHT mode commands, you can also perform statistical calculations and graph statistical data using the same procedures that you use in the STAT mode. Use this mode to store graph functions and to draw graphs using the functions. Use this mode to store graph functions and to draw multiple versions of a graph by changing the values assigned to the variables in a function. Use this mode to store functions, to generate a numeric table of different solutions as the values assigned to variables in a function change, and to draw graphs. Use this mode to store recursion formulas, to generate a numeric table of different solutions as the values assigned to variables in a function change, and to draw graphs. Use this mode to draw graphs of conic sections. EQUA (Equation) PRGM (Program) TVM (Financial) LINK MEMORY Use this mode to solve linear equations with two through six unknowns, quadratic equations, and cubic equations. Use this mode to store programs in the program area and to run programs. Use this mode to perform financial calculations and to draw cash flow and other types of graphs. to make Use this mode to transfer memory contents or back-up data to another unit or PC. Use this mode to manage data stored in memory. SYSTEM Use this mode to initialize memory, adjust contrast, and to make other system settings. 1-2-3 1-2-3 Display Display k About the Function Menu Use the function keys (1 to 6) to access the menus and commands in the menu bar along the bottom of the display screen. You can tell whether a menu bar item is a menu or a command by its appearance. • Next Menu Example: Selecting displays a menu of hyperbolic functions. • Command Input Example: Selecting inputs the sinh command. • Direct Command Execution Example: Selecting executes the DRAW command. k About Display Screens This calculator uses two types of display screens: a text screen and a graph screen. The text screen can show 21 columns and 8 lines of characters, with the bottom line used for the function key menu. The graph screen uses an area that measures 127 (W) ⋅ 63 (H) dots. Text Screen Graph Screen The contents of each type of screen are stored in independent memory areas. Press !6(G T) to switch between the graph screen and text screen. uSupplementary Information 20050401 20050401 Supplementary information is shown at the bottom of each page in a " (Notes)" block. * indicates a note about a term that appears in the same page as the note. # indicates a note that provides general information about topic covered in the same section as the note. 20050401
