In mathematics, an exponential sum may be a finite Fourier series (i.e. a trigonometric polynomial), or other finite sum formed using the exponential function, usually expressed by means of the function
Therefore a typical exponential sum may take the form
summed over a finite sequence of real numbers xn.
