Course: Differential Equations
A First Course in Differential Equations (10th Edition) by Dennis G. Zill
Thomas Tunnell
Office Hours:
posted on IVCC website

Course Description:  Solution of ordinary differential equations of the first order and higher order with constant coefficients by exact methods, some equations with variable coefficients, systems of equations, Laplace transforms, and an introduction to numerical methods. Applications of all topics to problems arising in engineering and the physical sciences are studied.

Prerequisite: Credit or concurrent enrollment in MTH 2003.


You may make up a test if:
1) you know you will be absent on the day of a scheduled test and you arrange a time prior to the test to take it early.

2)Otherwise you may use your score on the final to replace the first missed exam. A second missed exam without a physician's  written excuse will result in zero for that exam.  Missed quizzes cannot be made up for any reason (this includes homework quizzes).

Note:  After missing your first exam, it is recommended that you take any other exams early so as to not have an unforeseen problem such as car trouble make you miss a second exam.

(Note the following grading and testing information is subject to change by the instructor)

Grading   Testing
100-90% A 5-6 exams 100 pts each
89-80% B Periodic quizzes/hw quizzes 5-20 pts each
79-70% C Final exam 100 pts
69-60% D Homework  to turn in, pts TBA
0-59% F Group Exercises, pts TBA

To find average : (students total / total points possible) x 100

 IVCC withdrawal policy: Last day to withdraw is  4/10/14

Effective Summer 2011, students will have the ability to initiate a withdrawal from classes. By completing the form in the Records Office or through the form located within WebAdvisor, the student is authorizing IVCC to remove him/her from the course. Entering the student ID number serves as the studentís electronic signature. IVCC has the right to rescind a withdrawal in cases of academic dishonesty or at the instructorís discretion.

Students should be aware of the impact of a withdrawal on full-time status for insurance purposes and for financial aid. It is highly recommended that students meet with their instructor or with a counselor before withdrawing from a class to discuss if a withdrawal is the best course of action for that particular student.

 More detailed information is available at and selecting the menu item for Withdrawals on the left side of the page.

Expected learning outcomes and related competencies:
Upon completion of this course the student should have demonstrated proficiency in the following:
1. knowledge of the fundamental concepts of differential equations.
2. knowledge of methods of solving some first-order differential equations.
3. solve modeling problems using first-order linear and nonlinear differential equations.
4. knowledge of the theory and solution of higher-order differential equations.
5. solve modeling problems using higher-order differential equations.
6. solve linear differential equations by the use of power series.
7. manipulate Laplace transforms and solve differential equations using Laplace transforms.
8. solve systems of linear first-order differential equations.

Homework Details:

Missed quizzes: cannot be made up for any reason (this includes homework quizzes).

School Closings and Class Cancellations:  In the event of inclement weather, please tune to a local radio station for possible school closings.  If an exam is scheduled for a day that the school is closed or class is cancelled, it will be conducted during the next scheduled class period.  Check IVCC's Class Cancellations (

Cheating: A score of zero will be given on any assignment where cheating occurs. Other disciplinary actions are at the discretion of the instructor and may include, but are not limited to being withdrawn from the course and possibly from IVCC.

Attendance: You are expected to attend all classes regularly. If absence is unavoidable, it is your responsibility to determine what you missed

Policy: All IVCC student policies apply to this class.

Special Needs: If you are a student with a cognitive, physical or psychiatric disability you may be eligible for academic support services such as extended test time, texts on tape, note taking services etc..  If you are interested in receiving academic support services, please contact the Special Populations Office at 224-0284, office B-204.

Possible Extra Credit
During class there will be some opportunities for students to receive extra credit for going to the board.  After the class is given a problem to work in class during a typical lecture, I will ask if anyone wants to go to the board and show what they did on the problem.  If you just show the problem, you will get 2 points extra credit.  If you explain what you did, you will get 5 points extra credit.  This will be discussed in more detail the first day of class.
