find the fourier series representation of the function
What is a Fourier series in physics?
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.
Why is the Fourier basis useful?
The Fourier basis is convenient for us in that this series already separates these components. Therefore, by careful observation of which parts of the function are even and which are odd, we can do the integrals separately knowing which terms vanish and which do not.
