The region
\(D\) shown in
Figure 12.4.13 along with a horizontal slice. The position of the horizontal slice can be adjusted with a slider labeled
\(k\text{.}\) The coordinates of the points at the left and right of the horizontal slice are shown (in terms of
\(k\)) and change as the slider is moved.
