中文简介: | 在这门免费课程中,矩阵被用作一种简洁的方式来表示数学中经常出现的线性方程组。第1节着眼于两个和三个未知数的联立线性方程,然后将思想推广到线性方程系统。第2节发展了求解线性方程组的策略。第3节着眼于矩阵的代数,并表明矩阵可以被认为是向量的推广。第4节介绍矩阵的逆。第5节使用线性方程组来介绍方阵的行列式。 |
课程简介: | In this free course, matrices are used as a concise way of representing systems of linear equations which occur frequently in mathematics. Section 1 looks at simultaneous linear equations in two and three unknowns and then generalises the ideas to systems of linear equations. Section 2 develops a strategy for solving systems of linear equations. Section 3 looks at the algebra of matrices and shows that matrices can be thought of as a generalisation of vectors. Section 4 introduces the inverse of a matrix. Section 5 uses systems of linear equations to introduce the determinant of a square matrix. |
关 键 词: | 线性方程组; 方阵的行列式; 线性方程系统 |
