Quick-Start Welcome 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. 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.
Quick-Start defc to highlight RUN and then press w. 2. Use This is the initial screen of the RUN mode, where you can perform manual 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 × 3 + 61 1. Press o to clear the calculator. 2.
Quick-Start 1. Press o. SET UP 2. Press ! m to switch the set up display. cccc1 (Deg) to specify 3. Press degrees as the angle unit. 4. Press J to clear the menu. 5. Press o to clear the unit. 6. Press cf*sefw. REPLAY FEATURES d e With the replay feature, simply press or to recall the last calculation that was performed. This recalls the calculation so you can make changes or re-execute it as it is.
Quick-Start FRACTION CALCULATIONS $ You can use the key to input fractions into calculations. The symbol “ { ” is used to separate the various parts of a fraction. Example: 1 15/16 + 37/9 1. Press 2. Press o. b$bf$ bg+dh$ jw. Indicates 6 7/144 Converting a Mixed Fraction to an Improper Fraction d/c While a mixed fraction is shown on the display, press improper fraction. ! $ to convert it to an d/c Press ! $ again to convert back to a mixed fraction.
Quick-Start EXPONENTS Example: 1250 × 2.065 1. Press o. 2. Press bcfa*c.ag. 3. Press M and the ^ indicator appears on the display. f . The ^5 on the display indicates that 5 is 4. Press an exponent. 5. Press xii w.
Quick-Start 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: θ ; distance from origin: r). Example 1: To graph Y = X(X + 1)(X – 2) 1. Press m. d, e, f, and c to highlight GRAPH, and then press w. 2. Use 3. Input the formula. v (v+b) (v -c)w 4. Press 6 (DRAW) or w to draw the graph. Example 2: To determine the roots of Y = X(X + 1)(X – 2) 1.
Quick-Start 1 (ROOT). Press e for other roots. 2. Press 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). 123456 2. Press 6 (g). 123456 3. Press 4. Use 3 (∫dx). d to move the pointer to the location where w. Next, use e to X = –1, and then press move the pointer to the location where X = 0, and then press w to input the integration range, which becomes shaded on the display.
Quick-Start 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 !Zcc1 1. Press (Grph) to specify “Graph” for the Dual Screen setting. 123456 J, and then input the two functions. v(v+b) (v-c)w v+b.cw 2. Press 3. Press 6 (DRAW) or w to draw the graphs.
Quick-Start def c 3. Use , , , and 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. w , and the enlarged area appears in the 4. Press inactive (right side) screen. DYNAMIC GRAPH Dynamic Graph lets you see how the shape of a graph is affected as the value assigned to one of the coefficients of its function changes.
Quick-Start 4 bw to assign an initial value 4. Press (VAR) of 1 to coefficient A. 1 2 23456 bwdwbw 5. Press (RANG) to specify the range and increment of change in coefficient A. 6. Press J. 6 (DYNA) to start Dynamic Graph drawing. 7. Press The graphs are drawn 10 times.
Quick-Start TABLE FUNCTION The Table 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. Press m. d, e, f, and c to highlight TABLE, and then press w. 2. Use 3. Input the formula. v(v+b) (v-c)w 4. Press table.
Handling Precautions • Your calculator is made up of precision components. Never try to take it apart. • Avoid dropping your calculator and subjecting it to strong impact. • Do not store the calculator or leave it in areas exposed to high temperatures or humidity, or large amounts of dust. When exposed to low temperatures, the calculator may require more time to display results and may even fail to operate. Correct operation will resume once the calculator is brought back to normal temperature.
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. You 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. Stored data can also be affected by strong electrostatic charge or strong impact.
