So, I have got see xi 1 for omega 1, xi 2 for omega 2 .. xi n for omega n . Now, if I just square them up and plot them this side,you see, then if you add them all up together, there will be xi 1 square + xi2 square +etcetera, and they will not be same, because tomorrow I can have instead of n 100, I can have 1000.
