HI plz help me this could someone verify it for me plz find attachement
clc; clear all; k=0; s=0; N=inf; for i=1:N s=s+(1/(k^2+1)); k=k+1; end syms x n a0=1/pi*int(cosh(x),pi,pi); an=1/pi*int(cosh(x)*cos(n*x),pi,pi); bn=1/pi*int(cosh(x)*sin(n*x),pi,pi); fs=0; for l=0:100 fs=fs+(an*cos(l*x)+bn*sin(l*x)) end fsfs+a0/2;

N=inf; s=1; for k = 1:N s=s+(1/(k^2+1)); end The Fourier series sum has a couple of errors. I would do the following: fs = a0/2; N = inf; for n = 1:N fs=fs+(an*cos(n*x)+bn*sin(n*x)); end

Matlab fourier series
A further simplification: Except for a0, the values of an and bn can be calculated inside the loop, so they don't have to be stored in advance.
