Using Graphs & Geometry
Tool function
Places and activates a trace point on
the graph, enabling you to trace a
function and identify points of interest
as they are encountered during the
trace.
Enables you to set the increment to use
between consecutive values jumped to
during Graph Trace.
Enables you to view the pathway of a
geometric or analytic object (such as a
function graph) on the work area. The
pathway has a delayed fade. As more
movement occurs on the work area,
older portions of the pathway fade. If
you temporarily halt movement, a
portion of the trace path remains
displayed.
Halts geometric trace and erases all
persistent pathways on the work area.
Tool function
Constructs a point defined in free space,
on an object, or at the intersection of
two objects.
Constructs a point defined on an object.
When the object is a function graph, the
coordinates are displayed.
Constructs a point at each intersection of
two selected objects.
Constructs an infinite line defined by
two points or by a point and a direction.
If you press Shift while creating the line,
you limit its orientation, relative to the
x-axis or the horizontal aspect of the
screen, by 15- increments.
