NIntegrate has the option EvaluationMonitor f[x_]:=Exp[x]*Sin[5x/2]; pts={};NIntegrate[f[x],{x,0,Pi},EvaluationMonitor:>AppendTo[pts, x]] 3.53665 Length[pts] 55 Plot[f[x],{x,0,Pi}, Epilog->{Red,Line[{{#,0},{#,f[#]}}]&/@pts},PlotRange->All,ImageSize->500]; Bob Hanlon ---- Thomas Schmelzer <thomas.??? at balliol.ox.ac.uk> wrote: > Hoi zame, > > I am using NIntegrate to run a few experiments.
