Quick-Start

2.Press b(Root).

Press efor other roots.

Example 3: Determine the area bounded by the origin and the X = –1 root obtained for Y = X(X + 1)(X – 2)

1. Press i4(G-SLV)c.

2. Press i(∫dx).

3.Use dto move the pointer to the location where X = –1, and then press w. Next, use eto

move the pointer to the location where X = 0, and then press wto input the integration range,

which becomes shaded on the display.
