Math 308

Important Information

  • Text: Linear Algebra with Applications, Second Edition, by Jeffrey Holt.
  • Technology Requirements for Autumn 2020: You will need internet access, a device that connects to the internet with a camera, and a way to produce and upload handwritten work (your cell phone wworks). If you don't have access to a computer, try The Student Technology Loan Program, and then talk to your instructor. You can find some documentation for Zoom below:
  • WebAssign: The first (easy) part of homework are problems done in Webassign. (You must use this UW-specific link to log in to Webassign. The general Webassign page will not connect to your UW account. If you are prompted for a class key, you are using the wrong website.) These problems are rather elementary and are meant to provide practice with mechanics and to serve as a first comprehension check of the material. A second set of homework problems will be taken from the Conceptual Problems described below.
  • WebAssign Help: You should aim to get WebAssign set up and working within the first week of classes. If you need help please attend the office hours held by the WebAssign representatives at the start of each quarter. These hours will be announced by your instructor. If your instructor forgets, please ask them. This is the best help you can get. If problems persist please contact Gina Dean at WebAssign by email: Please inform your instructor as well. Please do not go to the Math Advising office in Padelford for WebAssign help.
  • Conceptual Problems: More challenging homework problems are given in the Conceptual Problems in the table below. Your instructor will assign a selection from these problems each week, and include similar material in the exams.
  • Using Gradescope: Many assignments in your class, including possibly exams and quizzes, will be administered through GradeScope. Here are some tips and instructions on how to use Gradescope.
    • Gradescope Assignments -- Log in to Gradescope and begin an assignment, quiz or an exam.
    • Take an Online Exam using your phone -- login to Gradescope using a browser on your phone to upload a photo of your handwritten work. Its easier to read the questions on your computer, but the least complicated way to upload your answers is by taking photos from within the Gradescope page running in a browser on your phone. If you can read the questions on your phone, you don't even need to login to Gradescope on your computer.

    • The mobile apps for Google Drive and Dropbox also have great scanning functionality.

UW 308 Policies

  • Academic integrity: As stated in UW's policy on Academic Misconduct., University of Washington students are expected to practice high standards of academic and professional honesty and integrity. Among other things, this means that you are expected to adhere to the exam and quiz policies of this class.
    • Exam and Quiz Policy: All exams and quizzes will be administered online this quarter. Exams are open notes and you can use a scientific calculator. You may not use any of the following resources during exams: getting help from anyone during your exam, using any online tools, websites, or search engines, using any calculators that can do calculus or linear algebra, and generally using any materials other than your notes and your textbook.
  • Religious Accommodation Policy: Washington state law requires that UW develop a policy for accommodation of student absences or significant hardship due to reasons of faith or conscience, or for organized religious activities. The UW’s policy, including more information about how to request an accommodation, is available at Religious Accommodations Policy. Accommodations must be requested within the first two weeks of the course using the Religious Accommodations Request form.

Additional Resources

  • Exams: Old exams from Math 308 are given in the table below. Please be aware that there are slight variations among them in content and style. Please talk to your instructor about what is expected in your upcoming exams.
  • Applications: These Applications are provided to give you a sense of the wide variety of uses for linear algebra. Your instructor might talk about a few of them in lecture. You are encouraged to skim through them, although this material is generally not expected on exams
  • Videos: The geometry of linear algebra is an integral part of this course. These excellent YouTube videos are a way to get more geometric insight into linear algebra. Please check them out as your instructor covers the related topic in class.
