Text Books:
Elementary Differential Equations and Boundary Value Problems, 10th edition, by Boyce-DiPrima, Wiley, ISBN-10: 0470458313. We will cover 5.1-5.6, 6.1-6.6, 7.1-7.9, 8.1-8.3, 10.1-10.8 (subject to change).
Online homework:
We will use WebAssign for our homework online. Student log in: go to http://www.webassign.net/purdue/login.html and use the Career Account information to log in.
To obtain the code: There are two options:
- purchase the textbook and access code from Purdue University or Follett's Bookstores.
- purchase access code from WebAssign (with or without eBook). (The students can purchase the textbook from any other vendors.) The student has two weeks free trial period of using WebAssign.
Grading Policy:
Your course grade will be determined as follows: 20% from each mid-term exam, 30% from the final exam, 15% from online homeworks and 15% from hand graded homeworks.
Make-up Policy:
There will be no make-up exams (midterm and final) except in extreme circumstances (such as: death in immediate family, military obligation, etc.) at the discretion of the instructor. The instructor has to be informed IN ADVANCE by e-mail. You will be asked to provide proper documentation. There is no drop for the homeworks and no late homeworks. To compensate for that, your HW grade will be scaled by a factor 1.1 (namely, anyone obtaining 91% or above in HW will be scaled to 100%).
Re-grade:
If you disagree with the grading on a homework, you must provide a written explanation, including your reasons for disagreeing, and resubmit the work to TA's mailbox for regrading within one week after the work is first returned to the class.
Tests:
There are two in-class midterm exams and a comprehensive final exam. Calculators, books and notes are not allowed during the exams. Laplace transform table will be provided when it is needed.

ACADEMIC ADJUSTMENTS FOR STUDENTS WITH DISABILITIES
- If you have been certified by the Disability Resource Center (DRC) as eligible for academic adjustments on exams or quizzes see http://www.math.purdue.edu/ada for exam and quiz procedures for your mathematics course or go to MATH 242 for paper copies.
- In the event that you are waiting to be certified by the Disability Resource Center we encourage you to review our procedures prior to being certified.
For all in-class accommodations please see your instructors outside class hours, before or after class or during office hours, to share your Accommodation Memorandum for the current semester and discuss your accommodations as soon as possible.
Integrity:
Academic integrity is expected for all students at all times in this course. You are free (even encouraged) to work with other students to solve the homework problems. But, you are required to write up solutions for each assignment using your own words and explanations. Of course, you are required to do your own work on each exam.
Emergency Preparedness:
In the event of a major campus emergency, course requirements, deadlines and grading percentages are subject to changes that may be necessitated by a revised semester calendar or other circumstances beyond the instructor's control. The primary way to get information about changes in this course is via the section webpage (this page) and course Blackboard page. Learn more at http://www.purdue.edu/emergency_preparedness/ .
