(2 2) is valid and then to derive the coefficients cn by calculating the derivatives of f(x) at x = x0; in this way one gets Eq (2 3) In 1807 Jean Baptiste Joseph Fourier

[PDF] On Fourier Transforms and Delta Functions

The Fourier transform of a function (for example, a function of time or space) provides a sinusoids, and the properties of Dirac delta functions, in a way that draws many represented by Fourier series over a range of x values such as − 1 2
