• The following shows how the display of coordinates and the derivative changes

according to the Graph Type setting.

• Rectangular Coordinate Graph

• Polar Coordinate Graph

• Parametric Function Graph

• X = Constant Graph

• Inequality Graph

• The derivative is not displayed when you use trace with a built-in scientific func-

tion.

• Setting the Coord item in the set-up screen to “Off” turns display of the coordi-

nates for the current pointer location off.

Scrolling

When the graph you are tracing runs off the display along either the

x-

or

y-

axis,

pressing the

e

or

d

cursor key causes the screen to scroll in the corresponding

direction eight dots.

• You can scroll only rectangular coordinate and inequality graphs while tracing.

You cannot scroll polar coordinate graphs, parametric function graphs, or X =
constant graphs.

• The graph on the screen does not scroll when you are tracing while the Dual

Screen Mode is set to “Graph” or “G to T”.

• Trace can be used only immediately after a graph is drawn. It cannot be used

after changing the settings of a graph.

• The

x

- and

y

-coordinate values at the bottom of the screen are displayed using

a 12-digit mantissa or a 7-digit mantissa with a 2-digit exponent. The derivative
is displayed using a 6-digit mantissa.

• You cannot incorporate trace into a program.

• You can use trace on a graph that was drawn as the result of an output com-

mand (

^

), which is indicated by the “-Disp-” indicator on the screen.
