Exploring Graphs With Trace - Texas Instruments TI-83 Plus Manual Book

Exploring Graphs with TRACE

You can use the TI-83 Plus feature
TRACE
to move the cursor from one plotted point
to the next along a relation. Because the
Inequality Graphing application is running,
the displayed in the top left corner
Y
n
includes the relation symbol.
See section 3–18 in the TI-83 Plus
guidebook education.ti.com/guides for
detailed information about the
TRACE
feature.
Exploring Graphs with PoI-Trace (Point of Interest
Trace)
When you select PoI-Trace, the Inequality Graphing application
displays the points of interest ("intersections" of all lines, dotted
or solid). Use the arrow keys to move from one or to
Y X
n n
another and from one point of interest to another on the same
Y
n
or as detailed below. If an X-coordinate lies outside of the
X
n
window range ( and ), that point of interest will not be
Xmin Xmax
found.
