WebA trigonometric polynomial is equal to its own fourier expansion. So f (x)=sin (x) has a fourier expansion of sin (x) only (from [ − π, π] I mean). The series is finite just like how the taylor expansion of a polynomial is itself (and hence finite). In addition, b n = 0 IF n ≠ 1 because your expression is undefined for n = 1. A Fourier series is an expansion of a periodic function into a sum of trigonometric functions. The Fourier series is an example of a trigonometric series, but not all trigonometric series are Fourier series. By expressing a function as a sum of sines and cosines, many problems involving the function become easier to … See more The Fourier series can be represented in different forms. The sine-cosine form, exponential form, and amplitude-phase form are expressed here for a periodic function $${\displaystyle s(x)}$$. Sine-cosine form See more The Fourier series is named in honor of Jean-Baptiste Joseph Fourier (1768–1830), who made important contributions to the study of trigonometric series, … See more When the real and imaginary parts of a complex function are decomposed into their even and odd parts, there are four components, denoted below by the subscripts RE, RO, … See more Fourier series on a square We can also define the Fourier series for functions of two variables $${\displaystyle x}$$ and $${\displaystyle y}$$ in the square Aside from being … See more This table shows some mathematical operations in the time domain and the corresponding effect in the Fourier series coefficients. Notation: See more Riemann–Lebesgue lemma If $${\displaystyle S}$$ is integrable, $${\textstyle \lim _{ n \to \infty }S[n]=0}$$, $${\textstyle \lim _{n\to +\infty }a_{n}=0}$$ and See more These theorems, and informal variations of them that don't specify the convergence conditions, are sometimes referred to generically as Fourier's theorem or the Fourier theorem.
