👉 The Fourier series of a function f(x) is a series representation of its Fourier transform, which represents the frequency domain representation of the original signal. This function has many applications in various fields such as physics, engineering, and music analysis. The Fourier series can be used to analyze signals and their properties, including how they vary over time or change in amplitude. The Fourier series is a powerful tool for solving problems related to these topics.
