Trace lets you move a point along a graph and displays the coordinates for the current 
pointer location. You can also link the trace operation to the number table used to draw a 
graph, so the pointer jumps to the coordinates that are currently selected in the table. 

Starting the trace operation causes a crosshair pointer to appear on the graph. You can then 
press the cursor key or tap the graph controller arrows to move the pointer. The coordinates 
are displayed as you move the pointer. 

S To perform a trace operation 

Example:  To graph the function 

 = 

2

 – 3 and then use the trace operation to read  

coordinates on the graph 

 (1) 

Tap 

 to display the View Window dialog box, and then configure it with the following 

parameters. 

xmin = –5, 

xmax = 5, 

xscale = 1

 

ymin = –10,  ymax = 10,  yscale = 2

 

(2) On the Graph Editor window, input and store 

2

 – 3 into line

1, and then tap  to 

graph it. 

 

(3) Tap [Analysis], [Trace], or tap .

• The pointer will not be visible when it is located at a point outside the graph display 

area. 

• If “Error” appears in place of the 

 or 

 coordinate, it means that the current point is 

undefined. Press the left or right cursor key to move to a point that is defined.

 

(4) Press the left or right cursor key, or tap the left or right graph controller arrow.

• This moves the pointer along the graph, and displays the coordinates of the current 

pointer location.
