Quick-Star t viii We lcome to the world of graphing calculators. Quick-Start is not a complete tutorial, but it takes you through many of the most common functions, from turning the power on, to specifying colors, and on to graphing complex equations.
Quick-Start ix 2. Use defc to highlight RUN and then press w . This is the initial screen of the RUN mode, where you can perform manual calculations, and run programs. BASIC CALCULA TIONS With manual calculations, you input formulas from left to right, just as they are written on paper .
Quick-Star t x 1. Press o . 2. Press ! m SET UP to switch the set up display . 3. Press cccc 1 (Deg) to specify degrees as the angle unit. 4. Press J to clear the menu. 5. Press o to clear the unit. 6. Press cf* s ef w . REPLA Y FEA TURES With the replay feature, simply press d or e to recall the last calculation that was performed.
Quick-Start xi FRACTION CALCULA TIONS Y ou can use the $ key to input fractions into calculations. The symbol “ { ” is used to separate the various parts of a fraction.
Quick-Star t xii EXPONENTS Example: 1250 × 2.06 5 1. Press o . 2. Press bcfa*c.ag . 3. Press M and the ^ indicator appears on the display . 4. Press f .
Quick-Start xiii 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 coordi- nates (angle: θ ; distance from origin: r ).
Quick-Star t xiv 2. Press 1 (ROOT). Press e for other roots. Example 3: Determine the area bounded by the origin and the X = –1 root obtained for Y = X(X + 1)(X – 2) 1. Press !5 (G-Solv). 12345 6 2. Press 6 ( g ). 12 3 456 3. Press 3 ( ∫ dx ). 4.
Quick-Start xv DUAL GRAPH With this function you can split the display between two areas and display two graphs on the same screen. Example: To draw the following two graphs and determine the points of intersection Y1 = X(X + 1)(X – 2) Y2 = X + 1.2 1.
Quick-Star t xvi 3. Us e d , e , f , and c to move the pointer again. As you do, a box appears on the display . Move the pointer so the box encloses the area you want to enlarge. 4. Pr ess w , and the enlarged area appears in the inactive (right side) screen.
Quick-Start xvii 4. Press 4 (V AR) b w to assign an initial value of 1 to coefficient A. 1 2 3456 5. Press 2 (RANG) b w d w b w to specify the range and increment of change in coefficient A. 6. Press J . 7. Press 6 (DYNA) to start Dynamic Graph drawing.
Quick-Star t xviii TABLE FUNCTION The T able Function makes it possible to generate a table of solutions as different values are assigned to the variables of a function. Example: To create a number table for the following function Y = X (X+1) (X–2) 1.
•Y our calculator is made up of precision components. Never try to take it apart. •A void dropping your calculator and subjecting it to strong impact. •D o not store the calculator or leave it in areas exposed to high temperatures or humidity , or large amounts of dust.
xx Be sure to keep physical records of all important data! The large memory capacity of the unit makes it possible to store large amounts of data. Y ou should note, however , that low battery power or incorrect replacement of the batteries that power the unit can cause the data stored in memory to be corrupted or even lost entirely .
