Einstein Notation: Proofs, Examples, and Kronecker Delta

In this video, I continue my lessons on Einstein notation (or Einstein Summation Convention), by explaining how parentheses work in Einstein Notation. This is followed by an explanation of some Einstein Notation identities, non-identities, and the Kronecker Delta symbol. This should wrap up the videos on Einstein notation, because in the next video on Tensor Calculus, I'm going to go more in-depth into actual Tensor Algebra! Questions/requests? Let me know in the comments! Prerequisites: The videos before this one on this playlist:    • Tensor Calculus   Lecture Notes: https://drive.google.com/open?id=1hRj...
