A note on Lagrange’s method of variation of parameters. (English) Zbl 1138.34302

Summary: In this note we provide a geometrical interpretation for the basic assumptions made in the method of variation of parameters applied to second order ordinary differential equations. We also discuss a physical motivation drawn from celestial mechanics.
