Applied Linear Algebra

Assignments: The work you do outside class will play a major role in helping you learn the material for
this class. Read the assigned section—and work all practice problems—before coming to class each day.
After covering the material in class, work the assigned exercises, check your answers (in the back of the
text and/or the Study Guide), and ask for help when needed. Homework will not be handed in (unless
otherwise announced) but will be reviewed in class as needed. Most quiz and exam problems will be taken
from the textbook examples, practice problems, and assigned exercises (possibly with minor modifications).

Projects: Several projects involving the use of MATLAB will be assigned; these projects may be completed
individually or in teams as announced. No collaboration allowed between teams.

Quizzes: Quizzes may be given any day in class without prior notice. Missed quizzes will not be made up.

Exams: There will be three hour exams, tentatively scheduled for Wednesdays 4 February, 4 March, and
8 April (in class). The final exam (week of 27 April) will cover the entire course. No grade exemptions
from the final exam. If you want me to reconsider your score on an exam, you must return it to me—with
a written explanation of your request—within three days of when the exams are returned in class.

Late Work: Projects are due when stated and will not be accepted late; missed quizzes and exams will
not be made up. Exceptions may be made at my discretion in exceptional circumstances.

Grades: Your final score will be a weighted average of your scores on quizzes (10%), projects and any
other work handed in (15%), three hour exams (20% each for two highest , 15% for lowest ), and final exam
(20%). Final scores translate into letter grades by the scale 90–100 A, 80–89 B, 70–79 C, 60–69 D, 0–59 F
with no “ curve ”.

Code of Ethics: I take the Clarkson Code of Ethics seriously. Any violation will result in a score of zero
on the work in question (at best) and will be reported to the Academic Integrity Committee. Cheating
on an exam will result in a grade of F for the course. For more information, see the section on Academic
Integrity in the Clarkson Regulations. When in doubt, ask me in advance.

Course Learning Objectives:

• To learn the fundamental concepts of linear algebra in the concrete setting of Rn
• To learn to use linear algebra to solve problems from engineering and other fields
• To learn to use computer software to apply the techniques of linear algebra

Course Outcomes: Upon successfully completing this course you should be able to:

• perform basic matrix calculations
• set up and solve linear systems in applied problems
• identify a linear transformation and find and use its matrix representation
• explain the basic concepts of linear algebra (subspace, span, linear independence, basis, dimension)
• identify and work with these concepts in Rn
• compute determinants of matrices
• compute eigenvalues and eigenvectors of matrices
• use eigenvalues and eigenvectors to diagonalize matrices and to solve systems of differential equations
• find an orthonormal basis for a subspace
• find least-squares solutions of linear systems
• use MATLAB to solve applied problems involving linear algebra

In order to achieve these outcomes you should expect to spend about six hours per week doing the assignments
(reading and exercises) and projects, in addition to the three hours per week in class.
