I would propose deleting the "comments" section of this article since a) it duplicates the text of Fourier series and b) unless I am being really dense, the constants multiplying the integrals for $a_n$, $b_n$ are wrong (the 2 should be removed on the denominator).

- Yes, the formulas are wrong. Yes, it duplicates. I only wonder, what is called "Euler-Fourier formulas", the formulas for the coefficients of a Fourier series for the trigonometric system, or for an arbitrary orthogonal system.
