Course description

MATH 221 - INTRODUCTION TO MATRIX THEORY
Prerequisite: Math 176 or Math 182.
Modeling and applications are stressed throughout. Topics covered to solve and analyze these models are matrix algebra, systems of linear equations, determinants, vector algebra and geometry in Euclidean 3-space, eigenvalues, eigenvectors. The course will use Maple 11 for homework, hour exams and modeling and computational exams.

      You can download

      For Problem 1 (c) it should start Find a matrix K not P

      For problem 5 on Computer and Modeling test 3 look at Exercise 3.1.1 in your text. Also parts b and c should be combined into one part

      The matrix in part b should have the values from part c before you try to find the eigenvalues and eigenvectors.
