integration by parts

[‚int·ə′grā·shən bī ′parts]
(mathematics)
A technique used to find the integral of the product of two functions by means of an identity involving another simpler integral; for functions of one variable the identity is for functions of several variables the technique is tantamount to using Stokes' theorem or the divergence theorem.
