If you want to integrate over a finite interval and the default call to
NIntegrate doesn't give accurate results, it might be worth the try to
increase Maxrecursion, SingularityDepth, or in combination with
Method->GaussKronrod: GaussPoints->20 or even more.
If you supply more detailed information on your problem, we could propably
