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 .
