MATH 222 Course Syllabus -Summer 2013

NJIT Academic Integrity CODE:  All Students should be aware that the Department of Mathematical Sciences takes the University Code on Academic Integrity at NJIT very seriously and enforces it strictly.  This means that 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 University Code on Academic Integrity, students are obligated to report any such activities to the Instructor.

 

Math 222:  Differential Equations

 

 

Number of Credits:  4

 

Course Description:  Methods for solving ordinary differential equations are studied together with physical applications, Laplace transforms, numerical solutions, and series solutions.

Textbook:  Elementary Differential Equations and Boundary Value Problems, 9th Ed., by Boyce and DiPrima.                      Students are required to have a copy of the textbook  available in class  at the start of semester.

Prerequisites: Math 112 or Math 112H with a grade of C or better.

Instructor:   (for specific course-related information, follow the link below)

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

Homework & Quizzes:

15%

Common Midterm Exam I:

25%

Common Midterm Exam II:

25%

Final Exam:

35%


A final average grade of 60 is required to pass this class and a final average grade of 90 is required to earn a grade of A. NOTE:  This course needs to be passed with a grade of C or better in order to proceed to Math 321, Math 331, Math 371, Math 372, Math 432 or Math 473.

Drop Date:  Please note that the University Drop Date July 10, 2013 deadline will be strictly enforced.

Homework and Quiz Policy:  Homework Assignments chosen from the text are listed below. 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.

Attendance:  Attendance at all classes will be recorded and is mandatory. Please make sure you read and fully understand the Department’s Attendance Policy. This policy will be strictly enforced.

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

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

Exam 1:

June 19, 2013

Exam 2:

July 10, 2013

Final Exam:

August 8, 2013


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. Make sure you read and fully understand the department's Examination Policy. This policy will be strictly enforced.

Makeup Exam Policy:  There will be No make-up 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.
