Note About Tracing A Solution Curve - Texas Instruments TITANIUM TI-89 User Manual

If Fields = Do this:
FLDOFF •
You are prompted to select the axes for which you want to
enter initial conditions.
Your selections will be used as the axes for the graph.

•
With SLPFLD or DIRFLD, you can select initial conditions interactively regardless
Note:
of whether you enter initial conditions in the Y= Editor. With FLDOFF, you can select
initial conditions interactively. However, if three or more equations are entered, you must
enter a single value (not a list) as the initial condition for each equation in the Y= Editor.
Otherwise, a Dimension error occurs when graphing.

When you enter initial conditions in the Y= Editor or let
automatically, you can use ... to trace the curves. However, you cannot trace a curve
drawn by selecting an initial condition interactively. These curves are drawn, not plotted.
