When you’re done, you’ll have mastered the basic operation of this calculator and will be ready to proceed with the rest of this user’s guide to learn the entire spectrum of functions available. Each step of the examples in Quick-Start is shown graphically to help you follow along quickly and easily. When you need to enter the number 57, for example, we’ve indicated it as follows: Press ®0. Whenever necessary, we’ve included samples of what your screen should look like. If you find that your screen doesn’t match the sample, you can restart from the beginning by pressing the “All Clear” button |AC/°N] .

AnI- Calculator power turns off automatically if you do not perform any operation within the Auto Power Off trigger time you specify. You can specify either 10 minutes or 60 minutes as the trigger time. USING MODES This calculator makes it easy to perform a wide range of calculations by simply selecting the appropriate mode. Before getting into actual calculations and operation examples, let’s take a look at how to navigate around the modes. To select the RUN • MAT mode 1. Press m to display the Main Menu. 20070201 2 Quick-Start 2. Use ®®f® to highlight RUN • MAT and then press w. This is the initial screen of the RUN • MAT mode, where you can perform manual calculations, matrix calculations, and run programs. BASIC CALCULATIONS With manual calculations, you input formulas from left to right, just as they are written on paper. With formulas that include mixed arithmetic operators and parentheses, the calculator automatically applies true algebraic logic to calculate the result. Example: 15 x 3 + 61 1. Press a to clear the calculator. 2. Press 00®dfflE0@. Parentheses Calculations Example: 15 x (3 + 61) 1. Press mf*md Built-In Functions This calculator includes a number of built-in scientific functions, including trigonometric and logarithmic functions. Example: 25 x sin 45° Important! Be sure that you specify Deg (degrees) as the angle unit before you try this example. 20070201 3 Quick-Start Press to display the Setup screen. 2. Press (Deg) to specify degrees as the angle unit. 3. Press J to clear the menu. 4. Press a to clear the unit. 5. Press Cf* (S ®[ (W. REPLAY FEATURE With the replay feature, simply press d or e to recall the last calculation that was performed so you can make changes or re-execute it as it is. Example: To change the calculation in the last example from (25 x sin 45°) to (25 x sin 55°) 1. Press d to display the last calculation. 2. Press d to move the cursor (I) to the right side of 4 3. Press D to delete 4. 4. Press [ 5 ]. 5. Press w to execute the calculation again. 20070201 4 Quick-Start gl FRACTION CALCULATIONS You can use the |<$| key to input fractions into calculations. The symbol “ j ” is used to separate the various parts of a fraction. Example: 31/-,6 + 37/g 1. Press [AC^N]. 2. Press db $ bgffl d0@®§. Converting an Improper Fraction to a Mixed Fraction While an improper fraction is shown on the display, press |shift| M mixed fraction. to convert it to a c c Press |shift| Ml again to convert back to an improper fraction. Converting a Fraction to Its Decimal Equivalent While a fraction is shown on the display, press equivalent. F«D to convert it to its decimal Press Ml again to convert back to a fraction. Indicates 871/ 144 20070201 5 Quick-Start EXPONENTS Example: 1250 x 2.065 1. Press [AC^N]. 2. Press 0Cfl®C01®. 3. Press M and the A indicator appears on the display. 4. Press f . The A5 on the display indicates that 5 is an exponent. 5. Press |EXE]. ONBOARD FUNCTION MANUAL You can use the catalog function to display the command onboard function manual. The onboard function manual includes an explanation of the command, syntax information, one or more examples of how to use the command, and the function key sequence. Example: To display onboard function manual information for the nCr command. 1. Press |AQl. 2. Press |SHIFT] e (CATALOG). 3.

Onboard function manual GRAPH FUNCTIONS The graphing capabilities of this calculator makes it possible to draw complex graphs using either rectangular coordinates (horizontal axis: x ; vertical axis: y) or polar coordinates (angle: 9 ; distance from origin: r). All of the following graphing examples are performed starting from the calculator setup in effect immediately following a reset operation. Example 1: To graph Y = X(X + 1)(X - 2) 1. Press MENU . 2. Use d®®® to highlight GRAPH, and then press X . 3. Input the formula. 4. Press (DRAW) or X to draw the graph. 20070201 7 Quick-Start Example 2: To determine the roots of Y = X(X + 1)(X - 2) 1. Press 05 (G-SLV). 2. Press (ROOT). Press ® for other roots. Exam...
