## Learning Objective

• At the end of the course, we hope that the students are able to solve all kinds of first order ordinary differential equations. Students also may solve higher order differential equations. Similarly we expect students should know how to use Laplace transform when they are solving ODE. Finally, students will learn some methods involving Fourier series.
