Course Outline

  • Chapter 1: Matrices, Vectors, and Systems of Linear Equations (11 days)
    Sections 1 - 4, 6 & 7, with selected applications in section 5 as time allows. Matrix operations and their properties, Linear combinations, Systems of linear equations, Gaussian elimination, Span of a set of vectors, Linear independence and dependence, and selected applications (time allowing)
    Note: Inclusion of Gaussian elimination (Section 9.1) is also appropriate at this time.
  • Chapter 2: Matrices and Linear Transformations (10 days)
    Sections 1, 3,4,7 and 8, with selected applications from sections 2, 5 and 6 as time allows. Matrix multiplication, Matrix inverses, Elementary matrices, Linear transformations of matrices, and applications (as time allows)
  • Chapter 3: Determinants (3 days)
    Sections 1 and 2. Introduction to determinants, Cofactor expansion, and Properties of determinants.
  • Chapter 4: Subspaces and Their Properties (8 days)
    Sections 1-5; Subspaces, Basis and dimension, Coordinate systems, and Matrix representation of linear operators. Note: Material from Chapter 7 can be incorporated with this discussion, as desired.
  • Chapter 7: Vector Spaces (3 days added to Chapter 4 material )
    Sections 1-4 General vector spaces, Subspaces, Linear transformation, Basis and dimension, and Matrix representation of linear operators.
  • Chapter 5: Eigenvalues, Eigenvectors, and Diagonalization (4 days)
    Section 1, with optional coverage of other sections (section 3 recommended if time allows) Eigenvalues and eigenvectors. Diagonalization of matrices and/or other applications as time allows.
