A series of linear algebra lectures given in videos.
Linear Algebra: Introduction to the inverse of a function
Proof: Invertibility implies a unique solution to f(x)=y for all y in co-domain of f.
Introduction to surjective and injective functions
Relating invertibility to being onto (surjective) and one-to-one (injective)
Determining whether a transformation is onto
