![]() ![]() This procedure won't always work so well (since the 2D integration grid resulting from this procedure won't always be optimal), but should work well enough when the integrand is such that integrations over x and y are sufficiently "decoupled". Which is not blazing fast, but reasonably fast. The Edit 1 answer by ruebenko is the right first answer for general situations like this, that is, add the option Method -> ]//Timing (It can be found by searching for 'NIntegrateExplorer' in the help browser. See the tutorial example 'GUIKit Example: NIntegrate Explorer' in the documentation. Corporate Consulting Technical Consulting WolframAlpha Business Solutions Resource System. This caused a lot of headache for me recently when I encountered such behavior in one. ![]() gives a numerical approximation to an integral with InterpolatingFunction. Ruebenko's answer and the comments from user1091201 and Leonid together combine to give the right answers. One can also use the 'NIntegrate Explorer' to build knowledge or proficiency in determining NIntegrate's methods by the plots of the sampling points.

Clearly Mathematica ignores the fact that fx is zero outside of 0,1.

As of Version 6.0, NIntegrate natively supports InterpolatingFunction objects. ![]()
