**Recent Updates**

**[02.05.2013]** **Recitation schedule and instructors, office hours, course materials, grades and other information will be at Stellar.**

## Texts:

**(1).** Edwards and Penney, Elementary Differential Equations with Boundary Value Problems, Fifth or Sixth edition

**(2).** 18.03: Differential Equations Notes and Exercises (available at Copy Tech, Basement, Bldg. 11)

## Grading:

The homework, hour tests and final exam are each worth roughly one third of the total points, which will be used to calculate grades. But in addition, to pass the course, you must pass the final.

## Homework:

There are 9 problem sets due on Fridays at 12:55pm in 2-106. Solutions will be posted on Friday afternoons.

**Late homework: ** Recitation instructors may grant an extension for one problem set per term with no penalty. When you make up this problem set, you may not look at the posted solutions or talk to students who have seen the solutions.

## Exams:

There are three in-class hour exams on February 27, March 20, and April 24 (all Wednesdays). There will be a comprehensive three-hour exam during Final Exam Week at a time to be announced.

## Collaboration:

Collaboration on homework is encouraged, but you should think through the problems yourself or else you will have trouble on the exams. You must write up your problem set in your own words. You may talk to people and use materials not explicitly recommended on our web site, but only with attribution. You will be asked to identify your sources on each problem set. Failure to attribute your sources may constitute plagiarism.

## Tutoring:

Mon through Thu at 3:00–5:00 and 7:30–9:30 in room 4-159.
