**Course Description**: First and second order
ordinary
differential equations, with emphasis on the linear case. Methods of
integrating
factors, undetermined coefficients, separation of variables, variation
of parameters, power series, Laplace transforms.

**Prerequisite:** Math 221 and either 203 or permission of the
Instructor.

**Grading Policy: ** Your grade will be based on 15% from
your
homework, 50% from the three midterms and 35% from the final exam.
