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. Press bf*d+gbw. Parentheses Calculations Example: 15 . (3 + 61) 1. Press bf*(d +gb)w. Built-In Functions This calculator includes a number of built-in scientific functions, including trigonometric and logarithmic functions. Example: 25 . sin 45° Important! Be sure that you specify Deg (degrees) as the angle unit before you try this example. Quick-Start Quick-Start 1. Press o. SET UP 2. Press!mto switch the set up display. 3. Press cccc1(Deg) to specify degrees as the angle unit. 4. Press Jto clear the menu. 5. Press oto clear the unit. 6. Press cf*sefw. REPLAY FEATURES With the replay feature, simply press dor eto recall the last calculation that was performed. This recalls the calculation so you can make changes or re-execute it as it is. Example: To change the calculation in the last example from (25 . sin 45°) to (25 . sin 55°) 1. Press dto display the last calculation. 2. Press dtwice to move the cursor under the 4. 3. Press f. 4. Press wto execute the calculation again. Quick-Start 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 o. 2. Press b$bf$ bg+dh$ jw. Indicates 67/144 Converting a Mixed Fraction to an Improper Fraction d/c While a mixed fraction is shown on the display, press !$to convert it to an improper fraction. d/c Press !$again to convert back to a mixed fraction. Converting a Fraction to Its Decimal Equivalent While a fraction is shown on the display, press Mto convert it to its decimal equivalent. Press Magain to convert back to a fraction. Quick-Start Quick-Start EXPONENTS Example: 1250 . 2.065 1. Press o. 2. Press bcfa*c.ag. 3. Press Mand the ^ indicator appears on the display. 4. Press f. The ^5 on the display indicates that 5 is an exponent. 5. Press w. Quick-Start 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: .; distance from origin: r). Example 1: To graph Y = X(X + 1)(X – 2) 1. Press m. 2. Use d, e, f, and cto highlight GRAPH , and then press w. 3. Input the formula. v(v+b) (v-c)w 4. Press 6 (DRAW) or wto draw the graph. Example 2: To determine the roots of Y = X(X + 1)(X – 2) 1. Press !5(G-Solv). 1 Quick-Start Quick-Start 2. Press 1(ROOT). Press efor 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). 6 12345 2. Press 6(g). 123456 3. Press 3(.dx). 4. Use dto move the pointer to the location where X = –1, and then press w. Next, use e to move the pointer to the location where X = 0, and then press wto input the integration range, which becomes shaded on the display. Quick-Start 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 1. Press !Zcc1(Grph) to specify “Graph” for the Dual Screen setting. 123456 2. Press J, and then input the two functions. v(v+b) (v-c)w v+b.cw 3. Press 6 (DRAW) or wto draw the graphs. BOX ZOOM Use the Box Zoom function to specify areas of a graph for enlargement. 1. Press !2(Zoom) 1(BOX). 2. Use d, e, f, and cto move the pointer to one corner of the area you want to specify and then press w. Quick-Start Quick-Start 3. Use d, e, f, and cto 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. Press w, and the enlarged area appears in the 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. Example: To draw graphs as the value of coefficient A in the following function changes from 1 to 3 Y = AX2 1. Press m. 2. Use d, e, f, and cto highlight DYNA , and then press w. 3. Input the formula. aAvxw 4 12356 Quick-Start Quick-Start 4. Press 4 (VAR) bwto assign an initial value of 1 to coefficient A. 1 23456 5. Press 2(RANG) bwdwbw to specify the range and increment of change in coefficient A. 6. Press J. 7. Press 6(DYNA) to start Dynamic Graph drawing. The graphs are drawn 10 times. v v^ v^ Quick-Start 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. 2. Use d, e, f, and cto highlight TABLE , and then press w. 3. Input the formula. v(v+b) (v-c)w 4. Press 6 (...
