• What you need :
• Log in to WebAssign here to read and submit homework. 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.

• Recommended Textbook Boyce and Diprima, Elementary Differential Equations and Boundary Value Problems or Elementary Differential Equations. Any edition is fine. Older editions cost less. Paperback version called Introduction to Differential Equations is available at the bookstore.

Math 307 Grade Policy. Beginning Autumn 2017, the department of mathematics has adopted a grade policy for this course. The median course grades for each section of Math 307 taught during the regular academic year will generally fall within the range of 3.0 +/- 0.2 .
