200702010-1-1Getting Acquaintedu GraphsAs a general rule, graph operations are shown onfacing pages, with actual graph examples on the righthand page. You can produce the same graph on yourcalculator by performing the steps under the Procedureabove the graph.Look for the type of graph you want on the right handpage, and then go to the page indicated for that graph.The steps under “Procedure” always use initial RESETsettings.The step numbers in the “Set Up” and “Execution” sections on the left hand page correspondto the “Procedure” step numbers on the right hand page.Example:Left hand page Right hand page3. Draw the graph. 3 5 (DRAW)(or w )u Command ListThe PRGM Mode Command List (page 8-7) provides a graphic fl owchart of the variousfunction key menus and shows how to maneuver to the menu of commands you need.Example: The following operation displays Xfct: [VARS]- [FACT]- [Xfct]u Page ContentsThree-part page numbers are centered at the top ofeach page. The page number “1-2-3”, for example,indicates Chapter 1, Section 2, page 3.u Supplementary InformationSupplementary 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 sectionas the note.5-1-1Sample Graphs5-1-2Sample Graphs200702015-1 Sample Graphskkkkk How to drawa simple graph(1)DescriptionTo draw a graph, simply input the applicable function.Set Up1.

Each file(Spreadsheet) contains a 26-column ⋅ 999-line spreadsheet. In addition tothe calculator’s built-in commands and S • SHT modecommands, you can also perform statistical calculations andgraph statistical data using the same procedures that you usein the STAT mode.GRAPH Use this mode to store graph functions and to draw graphsusing the functions.DYNA Use this mode to store graph functions and to draw multiple(Dynamic Graph) versions of a graph by changing the values assigned to thevariables in a function.TABLE Use this mode to store functions, to generate a numerictable of different solutions as the values assigned tovariables in a function change, and to draw graphs.RECUR Use this mode to store recursion formulas, to generate a(Recursion) numeric table of different solutions as the values assigned tovariables in a function change, and to draw graphs.CONICS Use this mode to draw graphs of conic sections.EQUA Use this mode to solve linear equations with two through six(Equation) unknowns, quadratic equations, and cubic equations.PRGM Use this mode to store programs in the program area and to(Program) run programs.TVM Use this mode to perform financial calculations and to draw(Financial) cash flow and other types of graphs. to makeLINK Use this mode to transfer memory contents or back-up datato another unit or PC.MEMORY Use this mode to manage data stored in memory.SYSTEM Use this mode to initialize memory, adjust contrast, and tomake other system settings.20070201kkkkk About the Function MenuUse the function keys (1 to 6) to access the menus and commands in the menu baralong the bottom of the display screen. You can tell whether a menu bar item is a menu or acommand by its appearance.• Next MenuExample:Selecting displays a menu of hyperbolic functions.• Command InputExample:Selecting inputs the sinh command.• Direct Command ExecutionExample:Selecting executes the DRAW command.kkkkk About Display ScreensThis calculator uses two types of display screens: a text screen and a graph screen. The textscreen can show 21 columns and 8 lines of characters, with the bottom line used for thefunction key menu. The graph screen uses an area that measures 127 (W) ⋅ 63 (H) dots.Text Screen Graph ScreenThe 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.1-2-3Display1-2-2Display1-2-3Display200702011-2-2DisplayIcon Mode Name DescriptionS • SHT Use this mode to perform spreadsheet calculations.
