• 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.

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 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.

k Scroll
You can scroll a graph along its x- or y-axis. Each time you press f, c, d, or
e, the graph scrolls 12 dots in the corresponding direction.
