Homework Equations
The Attempt at a Solution
I can prove this using algebra, but how is it done
using inner product concepts? If someone could start me up with a hint,
I could get somewhere. Thank you!
Note: It is apparent that those sums could possibly be inner products of vectors,
but I can't see how going into inner product notation would help me out.
