u u u u u To draw an integration graph [Sketch]-[GRPH]-[G ∫dx]
You can graph an integration calculation performed using the function y = f ( x ).
Example To graph the following, with a tolerance of “tol” = 1
E
- 4:
∫
–2
1
( x + 2) ( x – 1) ( x – 3) dx
Use the following View Window parameters.
Xmin = –4
Ymin = –8
Xmax = 4 Ymax = 12
Xscale = 1 Yscale = 5
1. In the set up screen, specify “ Y=” for Func Type and then press J .
2. Input the integration graph expression.

3. Press w to draw the graph.
• Before drawing an integration graph, be sure to always press ! 4 (Sketch)
