• 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
function.
• Setting the Coord item in the set up screen to “ Off ” turns display of the
coordinates for the current pointer location off.
u u u u u 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.
