Syllabus for Math 4123 Partial Differential Equations
PREREQUISITES: Math 2633 Calculus III and Math 4113 Differential Equations.

CATALOG DESCRIPTION OF COURSE: Series solution of ordinary equations, Fourier series, classical second order partial differential equations, heat equation, wave equation, and Laplace's equation. Boundary-value problems and Sturm-Liouville theory.

COURSE PURPOSE: The purpose of this course is to introduce the advanced undergraduate mathematics and/or physics major to the theory and applications of classical elementary partial differential equations. This course will provide the necessary background, expertise, and experience that is required to solve elementary classical partial differential equations in 2 and 3 dimensions.

EXPECTED COURSE OUTCOMES: The student will be expected to achieve the following objectives:

1. Communicate with appropriate mathematical symbols.

2. Understand and be able to use the method of separation of variables to solve linear partial differential equations.

3. Understand and be able to use Fourier Series for the solution of linear partial differential equations.

4. Understand and solve Sturm-Liouville eigenvalue problems.

5. Understand and use the methods of infinite series solutions of ordinary differential equations and how they apply to Bessel's equation and other differential equations that arise from separation of variables.

6. Understand and apply all of the above to the solution of the heat equation, the wave equation, and Laplace's equation.

INSTRUCTIONAL MATERIALS: (Required Textbook) Elementary Applied Partial Differential Equations, Third Edition, Haberman, Prentice-Hall, 1998

INSTRUCTIONAL PROCEDURES: The expected course outcomes will be realized through a variety of instructional strategies to aid the students in construction of cognitive schemas . Those strategies include, but are not limited to, the following: expository-discussion, demonstration, inquiry, and group activities.

ADA COMPLIANCE: If any member of the class feels that he/she has a disability and needs special accommodations of any nature, whatsoever, the instructor will work with you and the University's Office of Student Affairs to provide reasonable accommodations to ensure that you have a fair opportunity to perform in this class. Please advise the instructor of such disability and the desired accommodations at the first class attended.


INCLEMENT WEATHER / DISASTER POLICY: The following are basic premises for the inclement weather policy at Northeastern State University:

1. Class will be held if at all possible.

2. It is the student's responsibility to receive the information when weather is questionable.

3. Neither students nor faculty are expected to risk life or limb.

4. Faculty members are obligated to hold classes if the University is not closed, unless the faculty member is unable to get to campus.
Policy: During times of inclement weather, decisions concerning day classes will be made by 6:00 a.m. in order for the media to be notified and for students to receive the announcement before they leave home. Decisions concerning night classes will be made by 3:00 p.m.

The following media will be notified regarding closing of the campus:
