Math 307: Dept of Math, Univ of Washington

Math 307 Summer Quarter 2020

  • All classes will be online. There will be three video lectures each week, as well as one live online class. Most will use Zoom. Your instructor will contact you with details. You will need a computer, internet access, and a way to produce and upload handwritten work. If you don't have access to a computer, try The Student Technology Loan Program.You can find some documentation for Zoom below:

  • What you need :
    • Log in to WebAssign here to read and submit homework. You must use this link to login to WebAssign. You do not need a course key. If you see a message requesting a course key, you are trying to log in from the wrong url.

      You will need to buy access ($22.95) and have two weeks to comply. You don't need to buy any other Cengage products. The WebAssign payment process can be a bit complicated. See these Detailed Instructions for paying for WebAssign access.
    • Textbook Introduction to Differential Equations by Boyce, Diprima, and Meade : You can access the etext from your class Canvas page. Access is free for 10 days, then it will cost $25. You pay the bookstore at this link. You must pay for the book before July 6th, 2020. After that you can no longer purchase the ebook. After your purchase, you can read the book online or download and use the VitalSource reader. You can print up to 10 pages at a time as well. The downloaded version doesn't expire.

      If you run into trouble, contact the University Book Store Course Materials Department by phone at 206-634-3400 x332 or by email

      If you prefer a paper version, any edition of Elementary Differential Equations and Boundary Value Problems or Elementary Differential Equations will do. A custom version is available through the bookstore. Older versions are cheaper. You don't need to buy the solutions manual. The WebAssign homework is different from the homework problems in the textbook, so the solutions manual will not be particularly useful.
