In this short video, I go over some very basic concepts in linear algebra that will be relevant to tensors later on in the series. These include Linear Transformations and General Transformations. I finish the video with the Chain Rule for Partial Derivatives (which will also come in handy in the future) expressed in terms of Einstein Notation.

My lecture series on Tensors assumed knowledge of Linear Algebra, so this should be a fairly elementary review for most people. Nonetheless, in my effort to be as self-contained as possible, I made this ‘detour’ video just in case people needed it. In any case, we have the foundation necessary to tackle the actual Mathematics of Tensors, starting from the next video in the series.
