WebThe proof of this theorem is very straight forward, we can use induction: rst show this is true for n= 2 case (which is already given by Theorem 2.4). Then if n= k 1 holds, using the fact that P n k=1 x k= P n 1 k=1 x k+ x n, we can easily show this is also true for n= k. Theorem 4.3 (Bessel’s equality and inequality) Let x 1;x 2;:::;x n be ...
