(2 pts) Construct the first three Fourier approximations to the square wave

(2 pts) Construct the first three Fourier approximations to the square wave function x < /2 -/2 < x < /2 /2 < x < F(x) = proj (f) =| F(x) = projT (f) =| F3 (x) = projT (f) = f(x): = { 1 -1 Using a calculator, graph the function and the first three Fourier approximations to see how the approximation matches the function f(x)
