### Course Objectives

The course introduces elements of linear algebra as needed to manipulate and solve linear, constant coefficient systems of first-order ODEs.  In the second part of the course, students are introduced to the most commonly used curvilinear coordinate systems and develop skill in setting up and solving double and triple integrals.  The final part of the course introduces the theorems and techniques of vector calculus essential to mathematical physics and further study in real analysis.

### Learning Outcomes

Upon completing this course, it is expected that a student will be able to do the following:
