To cite this article R. Suárez Antola, Remarks on an approximate formula for the period of conservative oscillations in nonlinear second order ordinary differential equations, Nonlinear Sci. Lett. Abstract In this article an approximate analytical formula for the period of a conservative nonlinear oscillator is derived optimally. A suitable selection of the weight function that appears in the objective functional allows a derivation of a simple result that has been shown to be a very good
