**Course Code**: B11001Y-A01

**Course Name**: Linear Algebra I (A)

**Credits**: 4.0

**Level**: Undergraduate

**Pre-requisite**: Not required

**Lecture Time**: 80 hrs

**Instructors**:

**Course Description**

This course is a required basic course for all undergraduates in all majors. It is required that students master the introductory knowledge and methods of linear algebra as well as the relevant basic knowledge of algebra. This course is divided into three types which are type A (Mathematical), type B (Science and Technology) and type C (Engineering). These three types have the same basic content (see the teaching content and class hours). However, the specific calculation and applications are paid more attention in type C; there is more theoretical analysis in type B; while the foundation for type A is rigorous theoretical proof.

Type A is suitable for those students who will continue to study mathematics, physics, computer and other subjects. Type B is suitable for those students who will study any majors other than mathematics in the future. Type C is suitable for those students who will study any majors other than math, physics and computer in the future.

Through this course, students should meet the following basic requirements: Master the introductory knowledge of linear algebra as well as the relevant basic concepts and basic methods of algebra; have a preliminary understanding and way of thinking in linear algebra that lays a foundation for linear algebra II and other courses.

**Teaching methods**

1. Two times a week and 80 minutes each time for teaching, the format is 50 minutes for classroom teaching, 10 minutes for rest and 30 minutes for classroom teaching.

2. One time a week and 100 minutes each time for exercises and discussion.

**Grading**

The assessment will take the class routine performance, the mid-term examination and the final examination, which will count for 30%, 30% and 40% each. The class routine performance includes homework, classroom discipline, attendance, discussion and so on. The mid-term and the final examination are close-book examinations.
