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