Purpose of class
Students will master the basic operations of matrices. Furthermore, to solve simultaneous linear equations by Gaussian elimination and to understand the relationship between the type of solution and the rank of matrix. To be able to compute determinants and determine the properties of matrices using determinants. To understand linear transformations on the plane.
Course description
Linear algebra is a fundamental mathematics in the field of science and engineering. In this lecture, students will learn the definition of a matrix and its basic operations, and then learn the general theory of simultaneous linear equations and computation of inverse matrices as applications. Students will also learn about determinants and their properties, linear transformations on the plane and its meaning.
Goals and objectives
  1. To be able to basic operations for matrix
  2. To be able to understand linear transformation on the plane.
  3. To be able to solve simultaneous linear equations by Gaussian elimination and to understand relation between type of solution and rank of the coefficient matrix.
  4. To be able to compute the determinant of matrices.
