Lecture Notes

Homework and Solutions

To get the maximum benefit from lectures, and to be successful in this course, students are expected to put forth a strong independent study effort. This includes carefully reading the text, preferably ahead of lecture, and diligently working on homework problems. In lectures, I will focus on important concepts and problem areas instead of just reiterating material in the book. The course covers linear equations, matrix algebra, determinants, vector spaces, eigenvalues and eigenvectors, orthogonality. The course schedule consists of two parts.

1. Week #1 ~ Week #7: Sections 1.1 ~ 1.5, 1.7 ~ 1.9, Sections 2.1 ~ 2.3.

2. Week #8 ~ Week #14: Sections 3.1, 3.2, Sections 4.1 ~ 4.6, Sections 5.1 ~ 5.3.

It is absolutely essential that you do the assigned homework-and additional problems if needed. Late submissions of homeworks will not be accepted. This course will have two exams (Exam 1: March 1, and Final Exam: May 3). No compensation for missed Final will be considered.

A course total score will be based on the following,

·         homework: 15 %

·         computer assignment: 5 %

·         attendance: 2 %

·         exam: 33 %

·         final: 45 %

This class will be graded roughly on the scale of 90 % = A range (A-, A), 80 % = B range (B-, B, B+), 70 % = C range (C-, C, C+), 60 % = D range (D, D+), 60%- = F.

Academic Integrity:  Please note that we take extremely seriously the university’s policy on the need for academic honesty in all your work.  Any form of dishonesty in an assignment will lead to a zero on an assignment and we reserve the right to give a grade of F for the course as well.  If needed, Student Conduct will be contacted.  Visit the following site for more information regarding what constitutes academic dishonesty and the WSU procedures for handling cases of academic dishonesty. http://www.conduct.wsu.edu/default.asp?PageID=343
