Homework Statement
The problem is I am unable to understand the proof. I understand how it is done but I do not know how it is related to the theorem. It is probably because I am unable to understand the notation of matrices, the one involving k.
It is given that
I=δ_ij
= 1 0 0...0
0 1 0...0
...0
...1
So now how do I relate k with it?
So before you explain to me what's going on, please elaborate on the notation.
Thank you.
