Most laws of physics are described by using differential equations. Therefore, understanding the properties of differential equations is necessary for those who want to study science and engineering. This course is a standard one-semester linear differential equations course that covers 1st and 2nd order ordinary differential equations (ODE) and systems of ODEs and Laplace transform. Then we will study the series solution of differential equations at ordinary and regular singular points. The final objective focuses on partial differential equations (wave equation, heat equation and Laplace equation), and Fourier series and boundary value problems

Single variable calculus (MATH101) is mandatory. Multivariable Calculus (MATH102) is not required, but it is strongly recommended to enroll the course along with this course. Applied Linear Algebra MATH203 is not needed either, but we will use terminologies such as vectors and matrices from time to time.

Homework will be given, but it will not be collected. However, at each recitation session quiz will be given and the quiz will be based on the problem set of previous week.

The final grade will be based on:
Quiz (20%) / Midterm (35%) / Final (45%)

We expect to have 10 quizzes, and one quiz with the least grade will be dropped.
