 Author Comment/Response Peter Pein 11/16/12 01:19am In Response To 'Re: numerical integration and limits of integra...'---------Hi, this is a possibility when one knows the range of integration. To write a little function that does a correct job in any case is simple: nintval[r_] := NIntegrate[f[x], {x, -r, r}, AccuracyGoal -> 8,(*(*either*)Method-> "LocalAdaptive",(*or sth. like*)*) MinRecursion -> Ceiling@Log[1 + Abs@r]] but in this case I would do Integrate[f[x],{x,-r,r}] to get 7 Sqrt[Pi/5] Erf[Sqrt[5] r] and then write a function like: intval[r_] := N[(7 Sqrt[\[Pi]/5] Erf[Sqrt[5] r]), {Infinity, 8}] to get an accuracy of 8 digits. hth, Peter URL: ,
