#What is the Fourier series actually? -Now, to begin proving that the Fourier series is a true fact let us begin with the following hypothesis: +Now, to prove that the Fourier series is indeed true, we begin with the following hypothesis: Let $f : \mathbb I \rightarrow \mathbb C$ be a continuous, periodic function where $I$ is some time interval(period of the function). Then it can be expressed as : $$ -- cgit v1.2.3
