• 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.

uScrolling
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.
