What is a Fourier series?

Fourier series is a representation of a periodic function as the sum of an infinite series of sines and cosines.

What is a Fourier series used for?

Fourier series is used to represent a periodic function as a sum of sine and cosine functions. It is used in various fields, including signal processing, physics, engineering, and mathematics.

What is Fourier series formula?

The formula for Fourier series is: f(x) = a_0/2 + ∑(a_ncos(nx2π/L) + b_nsin(nx2π/L)), where L is the period of the function, 'a_0' is the constant term, 'a_n' and 'b_n' are the Fourier coefficients.

What is a real life example of Fourier transform?

A real-life example of Fourier transform is in the compression of digital audio and images, where the transform is used to convert the data from the time or spatial domain to the frequency domain for more efficient storage and transmission.
