  • The FINAL EXAM for 220-01 will take place on WEDNESDAY, DECEMBER 16, 10:00 AM - 12:00 PM in FULMER 201.
    The exam is comprehensive and consists of problems which are taken from the following topics and are similar to assigned problems from our textbook.

    - Solve a system/examine if it has none/one/more solutions. Express solutions in vector parametric form.
    - Examine a linear transformation for being one-to-one/onto, find its standard matrix etc.
    - Prove a set is a subspace/find basis/dimension.
    - Find bases and dimensions of ColA, NulA.
    - Matrix algebra (multiplication etc.), inverses and their use, conditions for invertibility (the IMT Theorem).
    - Find determinants/apply their properties.
    - Find characteristic equations, eigenvalues, bases for eigenspaces.
    - Find orthogonal projections/decompose vectors.

  • Computer assignment (in pdf format with instructions): Due by December 10, in class.
       The links mentioned in the assignment :
         MATLAB Primer: introduction to MATLAB

  • Here are the midterm solutions: [pink exam]    [blue exam]

  • The midterm exam will take place in class Thursday, October 8. Material: Sections 1.1--1.9, 2.1, 2.2.
    Here is a sample test with solutions.

  • Here are the slides used in class (Tuesday 9/1/09) to introduce the notion of Echelon Form etc.

  • Tutoring Sessions for Math 220 will begin Tuesday September 8.
        Location: Stephenson Complex Downunder
        Time: Sunday – Thursday, 7 – 9 pm

  • Ther teaching assistant for this section is Giang Trinh (Neill Hall 125, gtrinh@math.wsu.edu). He will be available in his office on Mondays 12-1 pm.

  • Visit the Linear Albebra Toolkit. This is a collection of easy to use PERL scripts pertaining to the contents of a course in linear algebra (written by Przemyslaw Bogack).

  • If you would like to know a bit more about linear algebra and its applications as a research area, look at my linear algebra web page. You'll find links to professional organizations, industrial applications, and sites with historical content.

  • Safety on Campus: The University has developed resources and a Campus Safety Plan for students, faculty and visitors. Also visit the University Emergency Management web site to become familiar with campus safety information and emergency procedures. Finally, become familiar with the WSU ALERT site.
