WebMar 14, 2024 · The purpose of this paper is the evaluation of the Fourier transform of powers of the sinc function multiplied by monomials, also in the cases when log terms arise. Such evaluations appear only rarely in the literature. Some old sources are hardly available. Because of notations not in use today, several original works are difficult to read. We … Web5 years ago. (Edit): Because the original form of a sinusoidal equation is y = Asin (B (x - C)) + D , in which C represents the phase shift. So, here in this case, when our sine function is sin (x+Pi/2), comparing it with the original sinusoidal function, we get C= (-Pi/2).
