This plot shows a
of the expression-a value of X for which the
value of the expression is zero. The zero is located where the graph of
the expression crosses the horizontal axis.
Move the cross hairs to the approximate intersection of the graph and
the horizontal axis.

Digitize this estimate for the zero.
You'll use this point as an estimate for finding the exact zero of the
expression. (In case the expression has more than one root, the esti-
mate indicates which one you want.)
Return to the stack display.
The coordinates of the digitized point, represented by a complex
number, are in level 1. (Your coordinates may differ slightly from the
