DEplot( ode, dep-var, range, [ini-conds] )• ode is the differential equation to plot• dep-var is the dependent variable• range is the range of the independent variable• ini-conds is a list of initial conditions7.2 Ordinary Differential Equations • 261The following is a plot of the function satisfying both the differentialequation ode1 and the initial conditions ic1 above.> DEplot( ode1, y(t), 0..20, [ [ ic1 ] ] );10.8y(t) 0.60.40.20 5 10 15 20tYou can refine the plot by specifying a smaller stepsize.> DEplot( ode1, y(t), 0..20, [ [ ic1 ] ], stepsize=0.2 );10.8y(t) 0.60.40.20 5 10 15 20tIf you specify more than one list of initial conditions, DEplot plots asolution for each.> ic2 := y(0)=0, D(y)(0)=1;
