This is because any function could be expressed as a number of peaks at every position. -It turns out that the above function can be approximated as the sum of two cosines, namely, $\cos^{2n}(x) + cos^{2n+1}(x)$ +It turns out that the above function can be approximated as the difference of two cosines, namely, $\cos^{2n}(x) + cos^{2n+1}(x)$ <center>  </center> Summing these two functions we get the following: - ##What is the Fourier series actually?</b> |
