Linear Algebra 1 is a study of n-dimensional Euclidean spaces, systems of linear equations, matrix algebra, elementary matrices, vector spaces and subspaces, basis and dimension, linear transformations and matrix representations, determinants, eigenvalues and eigenvectors, and diagonalization.
Topics include orthogonal and unitary matrices and transformations; orthogonal projections; the Gram-Schmidt procedure; and best approximations and the method of least squares. Inner products; angles and orthogonality; orthogonal diagonalization; singular value decomposition; and other applications will also be explored.
