Description The paper is concerned with integrability of the Fourier sine transform function when f ? BV0(R), where BV0(R) is the space of bounded variation functions vanishing at infinity. It is shown that for the Fourier sine transform function of f to be integrable in the Henstock-Kurzweil sense, it is necessary that f/x ? L1(R). We prove that this condition is optimal through the theoretical scope of the Henstock-Kurzweil integration theory.
