Example To graph Y = sin X, and then determine the graph integration value and
area value for the region between the root of the minus value nearest
the origin and the root of the plus value nearest the origin
Integration value
Area value
• If there are 21 or more roots between the two roots you specify, an error will occur.
• Integral values and area values can be calculated for rectangular coordinate graphs only.
u To obtain the integration value and area value between two or more
intersection points of two graphs
1. Draw two graphs.
2. Press !5(G-SOLVE)6(g)3(∫d
x)3(INTSECT).
• The pointer will appear at the leftmost intersection currently on the graph screen.
• If there is no intersection point 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 intersection point 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 intersection point you want to use as the uppermost side
of the integration region.
• If there is only one intersection point 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.
Example To graph Y = sin X and Y = sin (
X −
2
π
), and then determine the
integration value and area value between two points of intersection you
specify
Integration value
Area value
• If there are 21 or more intersections between the two points of intersection you specify, an
error will occur.
• Integral values and area values can be calculated for rectangular coordinate graphs only.
