MA 227 - Multivariable Calculus

Review of matrix operations, Cramer’s rule, row reduction of matrices; inverse of a matrix, eigenvalues and eigenvectors; systems of linear algebraic equations; matrix methods for linear systems of differential equations, normal form, homogeneous constant coefficient systems, complex eigenvalues, nonhomogeneous systems, the matrix exponential; double and triple integrals; polar, cylindrical and spherical coordinates; surface and line integrals; integral theorems of Green, Gauss and Stokes.

**Prerequisites:** MA 124, MA 116

**Corequisites:** MA 221

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.
