Differential Equation Graphing
410
Note:
With SLPFLD or DIRFLD, you can select initial conditions interactively regardless
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.
Note about Tracing a Solution Curve
When you enter initial conditions in the Y= Editor or let
ncurves
graph solution curves
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.

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.
