Amplitudes of linear oscillations determined by linear homogenous differential equation of the second order and Liouville-Besge formulae

Miloje Rajović, Dragan Dimitrovski

In this paper we present some quadraturic aspects of solving the equation by means of quadratures. It has a special comparative value when estimating Sturm's zeros, "periods" and variable amplitudes in cases which are solvable by means other than quadratures (iterations).
