# 11: Green's Functions


A Green’s function is a solution to an inhomogenous differential equation with a “driving term” that is a delta function (see Section 10.7). It provides a convenient method for solving more complicated inhomogenous differential equations. In physics, Green’s functions methods are used to describe a wide range of physical phenomena, such as the response of mechanical systems to impacts or the emission of sound waves from acoustic sources.
