Course description and aims

This course focuses on the ordinary differential equations used in the analysis of linear systems and nonlinear systems. Topics include 1st order ordinary differential equations, n-th order ordinary differential equations, Fourier series, etc. and also include the functions of elementary solutions of ordinary differential equation. By combining lectures and exercises, the course enables students to understand and acquire the fundamentals of mathematical tools widely applicable to linear systems and nonlinear systems in engineering.
This course covers fundamentals of ordinary differential equations as a mathematical knowledge required to solve problems and develop mechanical engineering. By using a mathematical approach such as the differential operation method, students will experience the satisfaction of solving practical problems by using their mathematical knowledge acquired through this course.

Student learning outcomes

By the end of this course, students will be able to:
1) Explain linear systems and nonlinear systems in ordinary differential equations.
2) Explain the properties of elementary solutions using Wronski determinant.
3) Explain solving method of n-th order ordinary differential equations.
4) Explain the fundamentals of the functions of f general solutions.
5) Apply differential operator to solve problems.

Keywords

Ordinary differential equations, elementary solutions, differential operator, Fourier series, nonlinear ordinary differential equations, perturbation method.

Competencies that will be developed

✔ Specialist skills Intercultural skills Communication skills Critical thinking skills ✔ Practical and/or problem-solving skills

Class flow

At the beginning of each class, solutions to exercise problems that were assigned during the previous class are reviewed. Towards the end of class, students are given exercise problems related to the lecture given that day to solve. To prepare for class, students should read the course schedule section and check what topics will be covered. Required learning should be completed outside of the classroom for preparation and review purpose.
