Show that the se ##Why Fourier series is plausible?</b> To show that Fourier series is plausible, let us consider some arbitrary trignometric functions and see if it is possible to express them as the sum of sines and cosines: - $1. \cos(2x) = 1 - 2 \sin^2(x) -\therefore \sin^2(x) = 1/2 - \cos(2x)/2 -$ + $1. \cos(2x) = 1 - 2 \sin^2(x)$ +$\therefore \sin^2(x) = 1/2 - \cos(2x)/2$ + ##What is the Fourier series actually?</b> |
