Function aplet 3-9
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
For example, if you use the Root function to find the root
of a plot, you can use the result in calculations in HOME.
