NJIT HONOR CODE

All Students should be aware that the Department of Mathematical Sciences takes the NJIT Honor code very seriously and enforces it strictly.  This means there must not be any forms of plagiarism, i.e., copying of homework, class projects, or lab assignments, or any form of cheating in quizzes and exams.  Under the Honor Code, students are obligated to report any such activities to the Instructor.

 

Mathematics 222-007:

differential equations

FALL 2008

Course Schedule Link

 

 

       Instructor:  Prof. Muratov

       Textbook:  Elementary Differential Equations and Boundary Value Problems, 8th Ed., by Boyce and DiPrima.

       Grading Policy:  The final grade in this course will be determined as follows:

Å    Homework + Quizzes:

 

17%

Å    3 Common Midterms:

 

51%

Å    Final Exam:

 

32%

A final average grade of 60 is required to pass this class.  A final average grade of 85 is required to earn a grade of A. Please note that the University Drop Date November 3, 2008 deadline will be strictly enforced.

 

       Homework Policy:  Homework Assignments chosen from the text are attached to this document.  Students are required to work through these problems after each lecture in order to gain a better understanding of the course material.  Weekly quizzes will be based on these exercises.

       MATLAB:  MATLAB is a mathematical software program that is used throughout the science and engineering curriculum. Several MATLAB assignments will be given out. These assignments have been designed to help you learn how to use this software, as well as to help you visualize many of the concepts taught in class.

       Exams:  All sections of Math 222 will take three common midterm exams during the semester and one common final exam during the final exam week. Midterm exams are held on Wednesdays on the following days:

Exam 1

September 24, 2008

4:15 – 5:40pm

5:45pm to 7:10pm

Exam 2

October 29, 2008

4:15 – 5:40pm

5:45pm to 7:10pm

Exam 3

November 19, 2008

4:15 – 5:40pm

5:45pm to 7:10pm

Day sections will have common examinations on the above listed dates from 4:15pm to 5:40pm and evening sections from 5:45pm to 7:10pm.  A comprehensive final examination will be given at the end of the semester.  The date for this final examination will be announced at the end of the semester.

       Makeup Exam Policy:  There will be NO makeup exams during the semester. In the event the Final Exam is not taken, under rare circumstances where the student has a legitimate reason for missing the final exam, a makeup exam will be administered by the math department. In any case the student must notify the Math Department Office and the Instructor that the exam will be missed and present written verifiable proof of the reason for missing the exam, e.g., a doctors note, police report, court notice, etc., clearly stating the date AND time of the mitigating problem.

       Further Assistance:  For further questions, students should contact their instructor. All instructors have regular office hours during the week. These office hours are listed at the link above by clicking on the Instructor’s name. Teaching Assistants are also available in the math learning center.

       Cellular Phones:  All cellular phones and beepers must be switched off during all class times.
