19990401 Quick-Star t We lcome to the w orld of gr aphing calculators . Quick-Start is not a complete tutorial, but it takes you through many of the most common functions, from turning the power on, and on to graphing comple x equations.
19990401 2. Use defc to highlight RUN • MA T and then press w . This is the initial screen of the RUN • MA T Mode, where you can perf or m man ual calculations, matrix calculations, and run programs. BASIC CALCULA TIONS With manual calculations, you input f or m ulas from left to r ight, just as the y are wr itten on paper .
19990401 1. Press u 3 SET UP to display the SET UP screen. 2. Press cccc 1 (Deg) to specify degrees as the angle unit. 3. Press i to clear the menu. 4.
19990401 FRACTION CALCULA TIONS Y ou can use the $ ke y to input fractions into calculations. The symbol “ { ” is used to separate the various par ts of a fraction.
19990401 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 . The ^5 on the display indicates that 5 is an e xponent.
19990401 GRAPH FUNCTIONS The graphing capabilities of this calculator makes it possible to draw complex graphs using either rectangular coordinates (hor iz ontal axis: x ; ver tical axis: y ) or polar coordinates (angle: θ ; d istance from or igin: r ).
19990401 2. Press b (Root). Press e for other roots. Example 3: Deter mine the area bounded by the origin and the X = –1 root obtained for Y = X(X + 1)(X – 2) 1. Press i 4 (G-SL V) c . 2. Press i ( ∫ dx ). 3. Us e d to mov e the pointer to the location where X = –1, and then press w .
19990401 DUAL GRAPH With this function you can split the displa y between two areas and display two g raphs on the same screen. Example: To dra w the following tw o graphs and deter mine the points of intersection Y1 = X(X + 1)(X – 2) Y2 = X + 1.2 1.
19990401 3. Us e d e f c to move the pointer again. As you do , a bo x appears on the display . Mov e the pointer so the box encloses the area you w ant to enlarge.
19990401 4. Press 4 (V AR) b w to assign an initial v alue of 1 to coefficient A. 5. Press 2 (RANG) b w d w b w to specify the range and increment of change in coefficient A. 6. Press i . 7. Press 6 (D YNA) to star t Dynamic Graph drawing. The graphs are drawn 10 times .
19990401 TABLE FUNCTION The T able Function makes it possib le to generate a table of solutions as diff erent values are assigned to the variab les of a function. Example: To create a number tab le for the f ollowing function Y = X (X+1) (X–2) 1. Press m .
19990401 Handling Precautions •Y our calculator is made up of precision components. Nev er try to take it apar t. •A vo id dropping y our calculator and subjecting it to strong impact. •D o not store the calculator or lea ve it in areas exposed to high temper atures or humidity , or large amounts of dust.
19990401 Be sure to keep physical records of all important data! Low battery pow er or incorrect replacement of the batteries that po w er the unit can cause the data stored in memor y to be corrupted or ev en lost entirely . Stored data can also be aff ected by strong electrostatic charge or strong impact.
