How did fourier discover fourier series
Web3.1 Fourier trigonometric series Fourier’s theorem states that any (reasonably well-behaved) function can be written in terms of trigonometric or exponential functions. We’ll eventually prove this theorem in Section 3.8.3, but for now we’ll accept it without proof, so that we don’t get caught up in all the details right at the start. WebA Fourier series is a way of representing a periodic function as a (possibly infinite) sum of sine and cosine functions. It is analogous to a Taylor series, which represents functions as possibly infinite sums of monomial terms. …
