First order differential equations: applications.
Second order linear differential equations: methods and applications.
Series solutions of linear differential equations.
Laplace transform methods.

Exams: We will have an in-class midterm on April 30th. The final exam is on Monday, June 9, 11:30 am - 2:30 pm. No make-up exams will be given. If, under completely exceptional circumstances, you need to miss the midterm, the weight of the final will be adjusted accordingly. If you miss the final, you automatically fail the course.
