1 to 6 Remember- if f is an even function, f(-x) f (x). An even Fourier series, has only cosine terms and is used to approximate an even function, which we will denote it by: F(x)-a+a, cos(x) +a, cos(2x)+a, cos(3x) +.. Given an even function,f, on the interval [-π , we want to find the function Fe(x) so that f(x) This means that f(x) = ao + a, cos(x) +a2 cos(2x) +a, cos (3x)+ and, therefore, -F(x). jf(x)dr-fata, cos(x)+a,cos(2x)+a,cos(3x)+ dr....
