Information Science, Engineering and Mathematics majors and Mathematics minors.

1. To develop a rigorous understanding of the foundational ideas of linear algebra.
2. Develop facility in standard computations with matrices, linear systems and vector calculations.
3. To enhance comprehension by examing geometric interpretations of the foundational concepts.
4. To select and use technology (i.e. calculator or computer software) when appropriate in problem solving.
5. To develop an ability to recongize linear algebra concepts in the context of mathematical problems and applications and implement the corresponding processes.
6. To develop the process of making appropriate conjectures, finding suitable means to test those conjectures and drawing conclusions about their validy.
