Explore foundational linear algebra concepts through this collection of archived video lectures that covers essential topics from basic systems of equations to advanced coordinate transformations. Begin with systems of linear equations and their geometric interpretations in 2D, then progress through vector operations both algebraically and geometrically. Master linear combinations and span concepts across two detailed segments before diving into the relationship between one-to-one functions, onto functions, and invertibility. Examine invertible transformations and subspaces of R^n, including detailed analysis of null spaces and column spaces of matrices. Advance to coordinate system concepts by studying gridlines in nonstandard systems and learning to write vectors in different coordinate frameworks. Conclude with finding subspace dimensions, understanding rank relationships between column and null spaces, visualizing vectors across multiple coordinate systems, and deriving the change-of-basis formula.
