## Alternate coordinate systems (bases) (Khan Academy)

We explore creating and moving between various coordinate systems. (1) Orthogonal complements Orthogonal complements dim(v) + dim(orthogonal complement of v) = n Representing vectors in rn using subspace members Orthogonal complement of the orthogonal complement Orthogonal complement of the nullspace Unique rowspace solution to Ax = b Rowspace solution to Ax = b example (2) […]
