Essence of Linear Algebra (3Blue1Brown)

Grant Sanderson's animated series that builds a geometric picture of linear algebra. Chapters cover vectors, linear combinations, span and basis, linear transformations as matrices, matrix multiplication as composition, determinants, inverse matrices and column space, dot and cross products, change of basis, and eigenvectors and eigenvalues. It suits FSc and university students who can do matrix arithmetic but want to see what it means, and it pairs well with a lecture course such as MIT 18.06 taken afterwards.
