And if the Fourier coefficients of the shifted periodic function f(x-k) for the same fand for any positive constant k are A (n-0, 1, 2 ...) and ηπκ nлk B, (n-1, 2, ...), then show that A,a,, A₁, = a, cos- --b sin and L L nak Basin - +b, cos Find the relation between RMS values of f(x) and f(x-k). nak L L
