MATH 221
Fall 2011
 Section:
01
02

This is a course in the algebra of matrices and Euclidean spaces that emphasizes the concrete and geometric. Topics to be developed include solving systems of linear equations; matrix addition, scalar multiplication, and multiplication; properties of invertible matrices; determinants; elements of the theory of abstract finite dimensional real vector spaces; dimension of vector spaces; and the rank of a matrix. These ideas are used to develop basic ideas of Euclidean geometry and to illustrate the behavior of linear systems. We conclude with a discussion of eigenvalues and the diagonalization of matrices. 
Essential Capabilities:
Logical Reasoning, Quantitative Reasoning This course will train students in classical quantitative techniques and develop their ability to logically reason through mathematical proofs.
For a more conceptual treatment of linear algebra, students should enroll in MATH223.
