  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  

 -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).

 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 Setup screen.
