Expected Learning Outcomes and Methods of Evaluation
It is expected that students will be able to determine whether there is a solution to a system of linear equations, and if there is, to determine the solution. Students will be able to perform matrix operations, calculate the determinant and eigenvalues and eigenvectors of a matrix. Students will be able to determine whether a subset of R^n is a subspace, and if it is, determine its dimension and rank. Students will be able to explain their reasoning in a way that other students will understand.
