Math 307 Spring 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, preferably as a pdf. If you don't have access to a computer, try The Student Technology Loan Program.You can find some documentation for Zoom below:

  • Daily Information and Lecture Videos -- You will find lectures and refence to text book sections here.

  • Office hours -- links to office hours of math 307 instructors.
  • Some Additonal Practice Problems will be posted here every Monday. Solutions will be shown on Friday.

  • Exams -- Each section of Math 307 will have two exams; one in the fifth week and one in the 10th week of classes. They will be administered during your class time using Gradescope and Zoom. You will receive an email when your instructor adds you to a Gradescope course, sometime in the next few weeks. This will require a computer, internet access, and a way to scan your work and upload ( a smartphone with one of several apps will do, or you may be able to write on your tablet and produce a pdf that way.) . Here are some suggestions for creating and uploading pdf's:
  • WebAssign Office Hours via Zoom
General Information :
  • 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. Cengage is letting us use WebAssign for free this quarter. Follow these Instructions. Where you see references to the Calculus text, you should look for "Math 307" instead.

    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.

  • 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 April 23rd. After that you can't purchase the ebook. 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.
