A Particular Solutions Inhomogeneous Linear Second Order Ordinary Differential Equations Formula

A relatively simple formula is presented which allows a particular solution for an inhomogeneous second order linear ordinary differential equation to be written and evaluated immediately.
For second order linear ODEs this formula make the methods of undetermined coefficients and variation of parameters obsolete.
