Solution 10383: Shading Above or Below a Function on the TI-82
How can I shade above or below a function on the TI-82?
Using the shade command, the TI-82 can shade a specific area of the graphing window. This function is accessed by pressing [2nd] [DRAW] .
The first two arguments in the shade command define the area that will be shaded. The first is the lower bound; the second is the upper bound. So for example when working in the standard viewing window, to shade the area above x2, the following command would be entered on the home screen of the TI-82.
In this example x2 is the lower bound, and 10, the top of the viewing window, is the upper bound.
Please see the TI-82 guidebook for additional information.
