Differential Equations (3 credits)

Spring 2011 Syllabus

“A mathematician, like a painter or poet, is a maker of patterns. If his patterns are more permanent than theirs, it is because they are made with ideas.”

Professor G.H. Hardy (1877–1947), mathematician

TEXTBOOK:             Elementary Differential Equations, 2nd edition, Kohler & Johnson

COURSE DESCRIPTION: In this course we will study first order differential equations (linear and non-linear), second order differential equations, higher order differential equations, Laplace transforms and any other material we have time for!

COREQUISITE: MAT325

GENERAL EDUCATION CURRICULUM OBJECTIVES:  As a member of the Georgetown College academic community, you will cultivate skills in inquiry and analysis, critical and creative thinking, and quantitative literacy. This course will help you learn to think mathematically and prepare you for future academic and real-world pursuits. And don't forget that math is everywhere and without math we wouldn't have the Internet, the i-Pod, the i-Pad, cell phones or TV.

LEARNING OUTCOMES:  Students who pursue the study of mathematics are trained to solve problems and to communicate such solutions effectively. After completing this course, you should be able to demonstrate basic content knowledge of first and second order differential equations, higher order differential equations, and Laplace transforms

GRADING:    The following percentages will be used in grading:

15%     Quizzes

20%     Homework

45%    Tests (3 Tests — 15% each)

20%    Comprehensive Final Exam

NUMBER-TO-LETTER GRADE SCALE:   A:  93–100;   A/B:  88–92;   B: 83–87; B/C:  78–82;   C:  70–77;   D: 60–69;   F:  below 60. I reserve the right to adjust this scale slightly at the end of the semester.

CLASS:  Every student in MATH 345A will attend three 50-minute sections each week. The class will be in the scheduled classroom and will be the same days each week (M/W/F).

ATTENDANCE Policy: Attendance is not required but highly recommended. Please inform me in advance if you are planning on missing class.

QUIZZES:  There will be three to four in-class quizzes during the semester. These quizzes will be in-between each of your exams, including the final. Think of these quizzes as "mini-exams." Make-up quizzes will be given only in extreme circumstances determined by me.

HOMEWORK:  Homework will be due at the beginning of class and collected. I will only accept ONE late homework assignment. Any other homework assignment turned in after the start of class on the due date will not be accepted. Homework may be worked on in groups; however, all work turned in must be written up by you and you alone. You must attempt every problem and show work for every problem to receive credit for your assignment. Homework will be graded as follows: two to three questions will be graded for correctness for a total of 6 points; completeness will earn 4 points (i.e., you did every problem, correct or not).

TESTS:  Three tests will be given throughout the semester. Excused absences consist of medical issues or emergencies approved by me before the test is given. In the case of a documented excused absence, I most likely will replace the test score with the grade of your final. Unexcused absences will result in a zero score.

FINAL: There will be a cumulative final given on Tuesday, May 10 from Noon to 2 p.m.

WEB RESOURCES: Announcements, course information, homework assignments, review sheets, etc., will be posted on Moodle. It is your responsibility to check for any updates before each class.

HELP: There are two main sources for you to get help. First and foremost are your fellow classmates. I encourage you to work together on your homework assignments as well as studying and learning the material in groups. I am your second source. Please come to the posted office hours. If you cannot make any of the office hours, you may schedule an appointment.

ACADEMIC HONESTY POLICY: I take cheating very seriously. If you are caught cheating, you will most likely end up with a failing grade. Students should read the Academic Honesty Policy in the Honor System section of their Georgetown College Catalog.
