We cannot, in general, go from the Fourier series to the Fourier transform by the inverse substitution k = T!=2. There is a rapidly growing number of applications of these methods, so it is appropriate to invite students, as well as professionals, to the field. The relationship of any polynomial such as Q(Z) to Fourier Transforms results from the relation Z Dei!1t, as we will see. The Fourier transform is the extension of this idea to non-periodic functions by taking the limiting form of Fourier series when the fundamental period is made very large ( nite).
