Required Text Introductory Linear Algebra With Applications seventh edition by Kolman and Hill

Course Description This course covers linear equations, matrices, determinants, vector spaces, inner product spaces, linear transformations, eigenvalues and eigenvectors and their applications to engineering and business.

Course Outcomes

  • Be able to manipulate matrices and use them for modeling real world applications
  • Become familiar with vector spaces
  • Understand the relationship between vector spaces, matrices, and linear transformations
  • Think abstractly in order to provide proofs involving matrices, vector spaces and linear transformations

Prerequisite A grade of C or better in Math 107 or equivalent.

Grading Policy Your letter grade will be based on your percentage of possible points.

A 90 -- 100%        C 70 -- 79%

B 80 -- 89%          D 60 -- 69%

Homework: .........................................….125 points

Midterm 1: Jan 23.....................…..…......125 points

Midterm 2: Feb 14................................…125 points

Midterm 3: Mar 13.....................………...125 points

Poster Session Project:  Feb 25.................100 points

Final Exam: Mar 26............................…....400 points

Exam Policy Students are to bring calculators, pencils or pens, and paper to each exam.  Grading will based on the progress towards the final answer, and the demonstration of understanding of the concept that is being tested, therefore, work must be shown in detail.  Any student who cannot make it to an exam may elect to take the exam up to two days before the exam is scheduled. If all homework is completed and no more than three homework assignments are counted late, then the midterm with the lowest score will be dropped.

Homework Policy   Homework will be turned in at the end of class on the date due. If a student has additional questions, that student may see me after class in my office and then turn in the homework by 5:00 PM. Homework that is turned in within one week of the due date will be counted as half credit.  Homework may be turned later than one week after the due date, but points will not be awarded. 

Extra Credit  Any student who has turned in every homework assignment may elect to work on an extra credit assignment or project that will count as additional points towards either a midterm or the final.

Poster Project  The project involves investigating an application of linear algebra. The display must be approximately 1 meter by 1.3 meters. You may write any equation by hand. You are encouraged to have Math View, Maple, or Origin assist you in the project. Ideally you should work on the project with one partner, but an exception can be made under special circumstances. Your abstract is to be a one-paragraph description of your project. It will be due on April 23.  Included in your abstract should be a set of references that you intend to use.  From 12:00 to 1:00 on February 25 you will be expected to stand by your project and answer questions from the judges and observers.  The projected will be graded on both content and presentation. 

Registration

1. You must register for this class at the Office of Admissions and Records.

2. You may drop the class with no penalty or mark on your record on or before Friday, January 31.

3. After January 31, you may drop the class and receive a grade of W until Friday, March 7.

4. After March 7, if you are enrolled, you will receive one of the following grades:  A,B,C,D,F or I (Incomplete, must be negotiated with the instructor and is only allowed in special cases).

In this class, it is your responsibility to drop the class in order to avoid an unwanted grade. You must go to the registrar by the above dates to avoid the unwanted grade.

HOW TO SUCCEED IN A MATH CLASS

  1.  Come to every class meeting.
  2.  Arrive early, get yourself settled, spend a few minutes looking at your notes from the previous class meeting, and have   you materials ready when class starts.
  3.  Read each section before it is discussed in class
  4.  Do some math every day.
  5.  Start preparing for the tests at least a week in advance.
  6.  Spend about half of your study time working with your classmates.
  7.  Take advantage of tutors and office hours, extra help can make a big difference.
