kReading Coordinates on a Graph Line

Description

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

Set Up

1.From the Main Menu, enter the GRAPH mode.

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).

*1The 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.
