you can specify the mehtod by: Method->Oscillatory other Possible settings for Method are GaussKronrod, DoubleExponential, Trapezoidal, Oscillatory, MultiDimensional, MonteCarlo, and QuasiMonteCarlo. GaussKronrod and MultiDimensional are adaptive methods. MonteCarlo and QuasiMonteCarlo are randomized methods, appropriate for high-dimensional integrals.
