On the Particular Solution of p y’’ + q y’+ r y = Φ

Abstract

We exhibit how to construct the particular solution of py''+qy'+ry=Q  when we know one solution of the corresponding homogeneous equation. Our approach motivates the method of variation of parameters.   We exhibit how to construct the particular solution of   when we know one solution of the corresponding homogeneous equation.
