k Reading 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. Draw the graph.

Execution

2. Press 1(TRACE), and a pointer appears in the center of the graph.*

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.
