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.

This course explores systems of linear equations, matrix algebra, determinants, and introduces vector spaces and their applications.

Topics include a continued discussion on vector spaces. Linear transformations and matrices are examined more fully. Inner products, eigenvalues and eigenvectors, and diagonalization are introduced and disucssed. Applications to linear algebra are also examined.

This short course will help authors of digital learning materials ensure that the time and resources they’re spending on their projects are put to good use.
