“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, *2^{nd} 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.
