Objectives for Math 317

Be able to:

  • use vector algebra, matrix algebra and dot products to manipulate vector and matrix equations.
  • find the solution set to a given linear system of equations in parametric form.
  • compute the echelon and reduced echelon forms of a matrix .
  • compute row space, column space, null space, left null space, rank of a matrix.
  • compute inverse matrices.
  • compute orthogonal projections on to vectors and hyperplanes.
  • compute determinants, and understand the basic properties of determinants.
  • compute orthogonal complements of a subspace
  • determine the dimension of a vector subspace
  • compute the standard matrix for a given linear transformation.
  • compute the matrix for a linear transformation with respect to a given basis.
  • compute an orthogonal basis from one that is not orthogonal.
  • find an orthogonal matrix that diagonalizes a given symmetric matrix.

Be able to prove simple theorems on fundamental properties of linear algebra. These could include the following.

  • Prove a given set is a subspace (or prove it is not).
  • Prove a given set of vectors is linearly independent (or prove it is not).
  • Prove a given transformation is linear (or is not).
  • Use key theorems such as the Rank-Nullity Theorem to deduce properties of a given linear transformation.
  • Prove whether a set of vectors forms a basis.

Students With Disabilities

If you have a documented disability and require accommodations, you should obtain a Student Academic Accommodation Request (SAAR) from the Disability Resources office (Student Services Building, Room 1076, 294-6624 or TDD 294-6335, disabilityresources@iastate.edu or accommodations@iastate.edu). Please contact your instructor early in the semester so that your learning needs may be appropriately met.

More information about disability resources in the Mathematics Department can be found at Current Students under the "Student disability accommodation policy" link.
