## Math 20D Introduction to Differential Equations Lecture B Spring 2011 Course Syllabus

Credit Hours:  4       Prerequisite:  Math 20C (or Math 21C) with a grade of C- or better

Catalog Description: Ordinary differential equations: exact, separable, and linear; constant coefficients, undetermined coefficients. Variations of parameters. Series solutions. Systems. Laplace transforms. Techniques for engineering. Computing symbolic and graphical solutions using Matlab.

Textbook:  Elementary Differential Equations, ninth edition, by William E. Boyce & Richard C. DiPrima; published by John Wiley & Sons, Inc.; 2009

Subject Material:  We shall cover parts of Chapters 1, 2, 3, 5, 6 and 7 of Boyce & DiPrima.

Reading:  Reading the sections of the textbook corresponding to the assigned homework exercises is considered part of the homework assignment; you are responsible for material in the assigned reading whether or not it is discussed in the lecture.  It will be expected that you read the assigned material in advance of each lecture.

Calculators:  Calculator use will not be permitted on exams. Graphing calculators (such as the TI-86 or TI-89) may prove useful in checking solutions to some of the homework problems, but they are not required for the course.

1. Use clean paper (graphed or lined is okay) that is not torn from a spiral notebook.
2. Write your name, ID number, and section clearly on the front page of your completed assignment.
3. Start the problems coming from each section at the top of a sheet of paper
4. Clearly number each solution and present them in numerical order.
5. Leave at least one line of space between each problem.
6. Write clearly and legibly.

MATLAB Lab Assignments:  Math 20D has a computational component based on MATLAB.   There will be four (4) MATLAB assignments which will be due as announced on the MATLAB Assignment Due Dates page, and a MATLAB final quiz. . page.   The MATLAB assignments may be found on the MATLAB assignment page.  Your MATLAB lab assignment grade will be based on the best three (3) of four (4) MATLAB lab assignments and the MATLAB final quiz.  No late MATLAB lab assignments will be accepted.

Midterm Exams:  There will be two midterm exams given during the regular lecture hour on Monday;   see the course calendar for the specific dates.    There will be no makeup exams.   You may bring one 8.5 by 11 inch handwritten sheet of notes with you to each midterm exam. No calculators will be allowed during the midterm exams.

Final Examination:  The final examination will be held at the following time.

• 11:30am - 2:30pm Friday, June 10 (See the course calendar.)
• The final examination will not be offered at an alternate time.
• It is your responsibility to ensure that you do not have a schedule conflict involving the final examination. You should not enroll in this class if you cannot sit for the final examination at its scheduled time.
• You may bring one 8.5 by 11 inch handwritten sheet of notes with you to the final examination.
• No calculators will be allowed during the final examination.

Regrades:  Midterm exams will be returned in the discussion sections. If you wish to have your exam regraded, you must observe the following rules:

• Return your exam immediately to your TA. Regrade requests will not be considered once the quiz or exam leaves the room.
• If you disagree with the TA's answer to your regrade request, you may ask for the instructor to review it. To do this, you must:
• Return your quiz or exam immediately to your TA and ask that they forward it to the instructor.
• Instructor review requests will not be considered once the quiz or exam leaves the room.
• If you do not retrieve your exam during discussion section, you must arrange to pick it up from your TA within one week after it was returned in order for any regrade request to be considered.
