3. Use
d
and
e
to move the pointer along the graph to the point at which you want to
display the derivative.
When there are multiple graphs on the display, press
f
and
c
to move between
them along the
x
-axis of the current pointer location.
4. You can also move the pointer by pressing
v
to display the pop-up window, and then
inputting coordinates.
The pop-up window appears even when you input coordinates directly.
To exit a trace operation, press
i

The pointer is not visible on the graph when
it is located at a point outside the graph
display area or when an error of no value
occurs.
# You can turn off display of the coordinates at the
pointer location by specifying “Off” for the “Coord”
item on the SET UP screen.
