Function aplet interactive analysis

From the Plot view ( ), you can use the functions on the FCN menu to find roots, intersections, slopes, and areas for a function defined in the Function aplet (and any Function-based aplets). See “FCN functions” on page 3-

10.The FCN operations act on the currently selected graph.

The results of the FCN functions are saved in the following variables:

•Area

•Extremum

•Isect

•Root

•Slope

Access FCN variables

For example, if you use the Root function to find the root of a plot, you can use the result in calculations in HOME.

The FCN variables are contained on the VARS menu.

To access FCN variables in HOME:
