comment Why is it important that a basis be orthonormal?
proximal, yes, indeed. I am asking what is the importance in different subfields in mathematics, physics or others(Fourier Series for example). I suppose that there are people with many different backgrounds and interests here, so if everyone could come up with something, it would be very informative.
