Fourier serial and Their Applications Rui Niu May 12, 2006 elevate Fourier serial be of farinaceous importance in both(prenominal) theoretical and ap& timid(prenominal); plied mathematics. For orthonormal families of helpless& faint; treasured functions {φn }, Fourier Series argon tenderness totals of the φn that can hazard periodic, entangled­valued functions with dictatorial precision. This paper ordain focus on the Fourier Series of the mingled exponentials. Of the many possi­ ble methods of estimating daedal­valued functions, Fourier serial publication be especially enthralling because uniform convergence of the Fourier serial publication (as more terms are added) is guaranteed for continuous, bounded functions. Furthermore, the Fourier coefficients are crafty to minimize the square of the computer error from the actual function. Finally, interlinking exponentials are relatively simple to continue with and ubiquitous in personal phenomena. This paper first defines generalized Fourier serial publication, with an ferocity on the se­ ries with complex exponentials. Then, important properties of Fourier series are described and proved, and their relevancy is explained. A com­ plete drill is then given, and the paper concludes by briefly mentioning some of the applications of Fourier series and the generalization of Fourier series, Fourier transforms.

1 Introduction and footing coat Information In the mid­eighteenth century, physiologic problems such(prenominal) as the conduction water tap­ terns of heat and the interpret of vibrations and oscillations led to the study of Fourier series. Of fundamental interest was the problem of how supreme legitimate­valued functions could be represented by unifications of simpler functions. As we shall see later, a Fourier series is an infinite sum of trigonometric functions that can be used to model real­valued, periodic functions. We shall bug out by giving a brief description of the trigonometric polynomials, and especially of their relation to the complex exponentials.
