The course builds on Calculus and Linear Algebra. It aims to equip students with useful solution methods for solving various types of ordinary differential equations (ODEs), introduce the fundamental theory of ODEs, and develop skills for modeling real phenomena by ODEs.
Upon successfully completing this course, you should be able to:
Solution methods for first-order ODEs including separable equations, first-order linear equations, exact DEs, Non-exact DEs with integrating factors, homogeneous DEs, Bernoulli’s equation and substitution techniques for ODEs.
Linear theory and solutions of linear ODEs: Linear theory: principle of superposition, Wronskian, Linear dependence/independence, Abel’s formula etc.. Solution techniques for linear homogeneous equations with constant coefficients, Cauchy-Euler equation and linear nonhomogeneous equations via method of undetermined coefficients and methods of variation-of-parameters.
Laplace transform: properties of Laplace transform and solution of initial value problems using Laplace transform.
Systems of Linear ODEs: eigen-value method for linear systems of equations and methods of undetermined coefficients and variation-of-parameter methods for nonhomogeneous systems.
Basic skills in modeling by ODEs.

These are the relevant SPMS-MAS Graduate Attributes.
1. Competence
a. Independently process and interpret mathematical theories and methodologies, and apply them to solve problems
b. Formulate mathematical statements precisely using rigorous mathematical language
c. Discover patterns by abstraction from examples
2. Creativity
a. Critically assess the applicability of mathematical tools in the workplace
The Continuous Assessment consists of 4 quizzes with multiple choice questions or short-answer questions that are designed based on the above outcomes. It also contains an 2-hour final examination. These will not only provide a comprehensive coverage of the knowledge points, but also encourage students to study constantly and develop the skills consistently.
Lectures (39 hours) | The implementation of learning objectives will be built upon well-designed and prepared course materials and interactive means of conducting lectures. Below are student-centered learning and teaching approaches in the lectures. 1) ODEs are rooted in applications and many are arisen from mathematical modeling of real phenomena. In the lecture, some motivated examples will be given to make students feel this course useful for their future career. 2) This course involves some deep theory, and more insightful examples and practice questions are important and useful for engaging students. 3) In view of the depth of some course contents, it will encourage discussions and critical thinking through properly designed topics and related questions. |
Tutorials (12 hours) | To better implement the learning outcomes, the tutorial questions will be designed for three levels of difficulty: i) basic questions related to concepts and definitions; ii) working-out questions on must-known methods and iii) open-ended questions for critical thinking. Moreover, some tutorial questions will be focused on helping student explore/learn some real life applications of ODEs. |

You are expected to complete all assigned pre-class readings and activities, attend all classes punctually and take all scheduled quizzes in due course. You are expected to take responsibility to follow up with course notes and course related announcements.
Good academic work depends on honesty and ethical behaviour. The quality of your work as a student relies on adhering to the principles of academic integrity and to the NTU Honour Code, a set of values shared by the whole university community. Truth, Trust and Justice are at the core of NTU’s shared values.
As a student, it is important that you recognize your responsibilities in understanding and applying the principles of academic integrity in all the work you do at NTU. Not knowing what is involved in maintaining academic integrity does not excuse academic dishonesty. You need to actively equip yourself with strategies to avoid all forms of academic dishonesty, including plagiarism, academic fraud, collusion and cheating. If you are uncertain of the definitions of any of these terms, you should go to the Academic Integrity website for more information. Consult your instructor(s) if you need any clarification about the requirements of academic integrity in the course.
