If Fields = FLDOFF Do this: • Press: @ 2Š You are prompted to select the axes for which you want to enter initial conditions. t is a valid selection. It will let you specify a value for t0. Your selections will be used as the axes for the graph. • You can accept the defaults or change them. Then press ¸. • Specify an initial condition as described for SLPFLD or DIRFLD. 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. Differential Equation Graphing 424
