Trigonometric Functions and Fourier Series

Trigonometric functions are well understood and useful in analyzing functions because they can be used to model periodic phenomena and have a wide range of applications in fields such as physics, engineering, and mathematics.
A Fourier series is a way of expressing a periodic function as a sum of sine and cosine waves with different frequencies, amplitudes, and phases.

Approximation of Arbitrary Functions

Fourier series can be used to approximate arbitrary functions, but they are particularly useful for functions that have a periodic component.
The Fourier series can approximate an arbitrary function by breaking it down into its component frequencies and representing each frequency with a sine or cosine wave.

Convergence Study

Fourier series are used to study the convergence of a function, which means determining whether the series converges to the original function as the number of terms increases.
The study of convergence focuses on determining the necessary conditions for the Fourier series to converge to the original function.

Coefficients of the Fourier Series

The coefficients of the Fourier series are determined by integrating the product of the function and the sine or cosine wave over one period.
The coefficients represent the amplitude of each frequency component in the function.
