Perform matrix operations, including matrix inversion. Translate linear systems into matrix equations, and use matrix inverses to solve, where appropriate. Perform vector operations in Rn and interpret them geometrically. Verify and/or refute the validity of vector space axioms in specific examples. Apply the vocabulary of vector spaces (linear combination, span, subspace, linear independence and linear dependence, basis, dimension, and orthogonal) to specific examples in Rn. Exemplify linear transformations in Rn and distinguish linear transformation from non-linear mappings. Solve first and Second Order Differential Equations Compute eigenvalues and eigenvectors interpret them geometrically, and use them to help analyze some applied situation. Solve Systems of Linear Differential Equations Write simple two or three-step proofs, and construct illustrative counterexamples.
