Could someone kindly explain whether the 90 degree phase difference between sine & cosine functions contribute to the fact that they are orthogonal? I just studied Fourier series and treating sines and cosines as vectors is fine for my brain to handle, but I can't tell whether the phase difference of 90 degrees is a coincidence relative to their orthogonality in an infinite dimension space. Just trying to understand what I learn.
Cheers.
