integration by parts

The formula for integration by parts can be derived from the product rule of differentiation:

$\;\text{d}(uv)=u\;\text{d}v+v\;\text{d}u$

Take the indefinite integral of both sides (neglecting the constant of integration)

$uv=\int u \;\text{d}v+\int v \;\text{d}u$

or in the standard form:

$\boxed{\int U \;\text{d}V=UV-\int V \;\text{d}U}$
