Classical Analysis and ODEs 2017-01-09 v2

Abstract

In this note, a general formula is proved. It expresses the integral on the line of the product of a function ff and a periodic function gg in terms of the Fourier transform of ff and the Fourier coefficients of gg. This allows the evaluation of some oscillatory integrals.
