Einstein Summation Convention #2

There are a couple of major mistakes in the video:
1. 1:10 the summation should run from 1 to n
2. 40:35 the final answer is actually (2+s) qj (Mijm + Mjim). I made the very mistake I emphasised earlier !

Credit goes to Prof. Dmytro Volin for the worksheet.

Alexander Farren further explores Einstein's Summation Convention, working through the problem sheet and encountering matrices and generalised coordinate systems.
