Fourier series: A Fourier series (/ˈfʊrieɪ, -iər/) 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.

Fourier series: In mathematics, the Fourier series, named after Joseph Fourier (1768—1830), refers to an infinite series representation of a periodic function ƒ of a real variable ξ, of period P: In the case of a complex-valued function ƒ(ξ), Fourier's theorem states ... [85%] 2024-01-04
Fourier series: Fourier series express a piecewise continuous, bounded, periodic function as a linear combination of orthogonal sine and cosine functions. The seeds of the modern theory were developed by Joseph Fourier. [85%] 2023-02-28 [Calculus]
Fourier series: of a function $f$ in a system of functions $\{\phi_n\}$ which are orthonormal on an interval $(a,b)$. The series $$ \sum_{k=0}^\infty c_k \phi_k $$ whose coefficients are determined by \begin{equation} \label{eq1} c_k = \int_a^b f(x ... (Mathematics) [85%] 2024-01-04
