Variation of Parameters Method via the Riccati Equation

If we know one solution of its associated homogeneous equation (HE) for a linear differential equation of second order (LDE), then other independent solution of HE and the particular solution of LDE are obtained via the Riccati equation. Our method is an alternative to the Lagrange ‘ansatz’.
