Letter grades for the course will be `curved', with the class average corresponding to the boundary between a C and a B.

Resources

  • Textbook website: Study guides, review materials, data sets, case studies and applications, and additional resources can be found here at a website for the course textbook.
  • Tutoring services: The Math Department offers tutoring services for this course. You can find out more here .
  • Demos: The Wolfram Demonstration Project has some nice linear algebra demonstrations. I'll try to list some here but I encourage you to explore the collection yourself. Note: you need Mathematica Player to run the demonstrations but you can download it for free from the Wolfram Demonstration Project website.
    Topic
    Linear Equations: Row and Column View

    • Homework

    Homework will be  posted at this website.  The homework will be collected each Thursday, starting on Thursday September 2. Each week a selection of the problems will be graded. The cumulative homework grade will contribute 15% of the final course grade.
