FOURIER SERIES Meaning and
Definition
-
Fourier series refers to a mathematical technique used to represent a periodic function as a sum of sine and cosine functions. It is named after the French mathematician Joseph Fourier, who first introduced the concept in the early 19th century.
In essence, Fourier series allows us to decompose a periodic function into a series of harmonic components that have different frequencies and amplitudes. The series can be expressed as an infinite sum or a finite sum, depending on the desired accuracy of the approximation. The terms in the series are determined by the Fourier coefficients, which represent the amplitudes of the individual sinusoidal components in the decomposition.
The main principle underlying Fourier series is that any periodic function can be expressed as a sum of sinusoidal functions, known as the fundamental frequency and its harmonics. These harmonics are integer multiples of the fundamental frequency and contribute to the periodic behavior of the original function. By applying the Fourier series, we can analyze and manipulate periodic functions more easily, as they are represented in terms of simpler sinusoidal components.
Fourier series find numerous applications in various fields, including physics, engineering, signal processing, and harmonics analysis. They are particularly useful for studying and understanding periodic phenomena, such as oscillations, vibrations, and signals. The Fourier series has also paved the way for more advanced concepts, such as the Fourier transform and Fourier analysis, which extend the analysis to non-periodic functions and continuous spectra.

Etymology of FOURIER SERIES
The word "Fourier" in the term "Fourier Series" is derived from the name of the French mathematician and physicist, Jean-Baptiste Joseph Fourier. Fourier made significant contributions to the field of mathematical analysis, particularly in the study of heat conduction and the analysis of periodic functions. He introduced the concept of Fourier series, which is a way to represent a periodic function as a sum of trigonometric functions. The method of Fourier series is widely used in various fields of science and engineering for analyzing and modeling periodic or quasi-periodic phenomena.
