Description
Trace lets you move a pointer along a graph and read out coordinates on the display.
Set Up

2. Draw the graph.
Execution
3. Press !1(TRCE), and a pointer appears in the center of the graph.* 1
4. 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.
5. 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 !1(TRCE).

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 Setup screen.
