几个反问题及其求解

Several Contrary Questions and the Methods of Finding the Solution

学好高等代数,不但要注重每一个正面问题,而且要熟悉一些问题的反问题.本文讨论了高等代数中矩阵的特征值特征向量、线性变换的核及线性方程组等问题的反问题,并给出了其求解方法.

In order to learn the advanced algebra well,we should not only lay stress on each direct question,but also he familiar with some questions＇ contrary question. This article has discussed separately four contrary questions in the advanced algebra, they are the matrix characteristic value characteristic vector,matix of tvansformation, kernel of linear transformation and the solution of linear equations. The methods of finding the solution are given.
