Textbook
Elementary Differential Equations, 11th Edition (2017) by William E. Boyce, Richard C. DiPrima, Douglas B. Meade
Text and online homework: We will use the textbook Elementary Differential Equations, 11th Edition (2017) by William E. Boyce, Richard C. DiPrima, Douglas B. Meade. An electronic copy of the textbook is integrated in the homework system Wiley-Plus that we will use for the class. When setting-up your account with Wiley plus there will be an option to purchase a hard copy of the book for a (small) extra-fee.
Create an account (be sure to use UMASS CAMPUS EMAIL as your username, type in the exactly same first name and last name as you used on SPIRE) and sign-up for your class using the discount code you purchased at https://www.wiley.com/WileyCDA/Section/id-830129.html. Please make sure to sign up for the correct section.
There is no required calculator for the course, although many students find them helpful. You will be allowed to use a calculator on exams , you must show all work other than arithmetic calculations. I recommend you to buy TI-89 calculator if you don't have one.
The grading of the course will be as follows. There will be a final exam worth 30%, Mid-term during the semester worth 30%, Homework worth 30%, written homework worth 10%. All scores will be scaled to a 0-100 scale before averaging.
The final will be cumulative, with some emphasis placed on topics covered after the first exam. The date and time of the final exam will be scheduled by the university. The final will only be given at that time, and not at any other time for any reason. In particular, adjust your travel plans accordingly; planning to leave for vacation before the final exam is a bad idea.
The dates of the exams during the semester are tentatively scheduled to be the following:

The best way to get help is to visit TA'S office hours: 4-6pm Monday to Thursday.
Drops, Withdrawals, and Incompletes
The last day to drop with no record, or to submit a Pass/Fail option, is Monday, Feb 5th. If you intend to drop, please do so as soon as possible; others may be waiting to enroll in your section. The last day to drop with a W is the mid-semester date, Thursday, Mar 7th.
An Incomplete is possible only if: (1) you had a compelling personal reason, e.g., serious illness; (2) your work has clearly been passing; and (3) there's a good chance you'll complete the course with a passing grade within the allotted time. Thus, failing work is no reason in itself for an Incomplete.
