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 correspond-
ing 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

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