u To calculate the integral value for a given range Use the following procedure to obtain integration values for a given range. 1. Draw the graph. 2. Press !5(G-SOLVE)6(g)3(∫dx)1(∫dx). If there are multiple graphs on the graph screen, one of them will start flashing. 3. Use f and c to move the flashing to the graph you want to select and then press w. 4. Use d and e to move the lower limit pointer to the location you want, and then press w. 5. Use e to move the upper limit pointer to the location you want. 6. Press w to calculate the integral value. Example Graph the function shown below, and then determine the integral value at (-2, 0). Y1 = x(x + 2)(x - 2) • You can also specify the lower limit and upper limit by inputting them on the 10-key pad. • When setting the range, make sure that the lower limit is less than the upper limit. • Integral values can be calculated for rectangular coordinate graphs only. u To obtain the integration value and area value between two or more roots of a graph 1. Draw a graph. 2. Press !5(G-SOLVE)6(g)3(∫dx)2(ROOT). • The pointer will appear at the leftmost root currently on the graph screen. • If there is no root on the display, the message "Not Found" will appear. In this case, press J. 3. Use d and e to move the pointer to the root you want to use as the lowermost side of the integration region, and then press w. 4. Use e to move the pointer to the root you want to use as the uppermost side of the integration region, and the press w. • If there is only one root on the display, the message "Not Found" will appear. In this case, press J. 5. Press w to calculate the integral value and area value. 5-57
