Fourier Series Coefficients (where did they come from?)
Learn how to derive the Fourier series coefficients formulas. Remember, a Fourier series is a series representation of a function with sin(nx) and cos(nx) as its building blocks. Meanwhile, a Taylor series is a series representation of a function with x^n as its building blocks. These are

We introduce the theory of Fourier series, which allows us to analyse a periodic function in terms an infinite series of simple sines and cosines. In this lecture, we show how to calculate the coefficients of the series using integrals over the period of the function.
