Math 307 Winter Quarter 2020



  • What you need :
  • Log in to WebAssign here to read and submit homework. You will not be able to login at any other 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. In partiular, you do NOT need Cengage Unlimited If you are having trouble logging in or paying for WebAssign, call the help number 800.354.9706. or contact your instructor. Don't go to the math advising office; they cannot help you with WebAssign.
    Math307A and Math307B will not use WebAssign -- Check your class website.

  • 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: If you are in section A B C D E or G, you can acccess the etext here. Other sections can access the etext from their Canvas pages. Access is free for 10 days, then it will cost $25. You pay the bookstore at this link 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 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.
  • 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.
