# Fourier Series Calculator

## What is a Fourier Series Calculator?

A Fourier Series Calculator is a tool that helps in analyzing and computing Fourier series, which are mathematical representations of periodic functions as a sum of trigonometric functions. This tool makes it easier for users to understand and work with Fourier series, which are used in various fields such as signal processing, engineering, and physics.

## How Does a Fourier Series Calculator Work?

A Fourier Series Calculator works by taking a periodic function as input and then breaking it down into a series of sine and cosine functions with different frequencies and amplitudes. The calculator then computes the coefficients of these functions to represent the original periodic function accurately.

Users can input the period of the function, specify the number of terms in the Fourier series, and choose the range of the coefficients. The calculator then generates the Fourier series representation of the function, which can be used for further analysis and calculations.
