## COURSE DESCRIPTION

This course is to teach applications of ordinary differential equations, and is more about techniques in solving problems, and there will be more examples, less proofs. The material covered includes techniques in solving first order linear equations, second and higher order linear equations, series solutions of second order linear equations, Laplace transform, systems of first order linear equations, and methods for the study of nonlinear equations.

## POLICIES

(1) There will be one homework per week. They will be assigned in each lecture and will be posted online. The homework will be due the following Monday at 4pm. Please leave it in the mailbox for Math 2a (practical). At most one late submission will be accepted, except medical reasons, or other serious difficulties (a note is needed from the dean's office).

(2) The final grade will be 50% homework, 20% midterm, 30% final.

(3) Collaboration policy: Discussions about homework are allowed, but the homework has to be written individually. No discussions on the midterm and final examinations.

## TOPICS COVERED

Techniques in solving first order linear equations, second and higher order linear equations, series solutions of second order linear equations, Laplace transform, systems of first order linear equations, and methods for the study of nonlinear equations.
