摘要
对几道抽象难解的线性变换考研题给出了简洁的矩阵证明,并由此深入讨论了线性变换与矩阵命题的转化,强调了高等代数教学中问题转化意识的培养和能力的提升。
The elegant correspondence relationship between linear transformation and matrix is discussed in detail first.Then based on this relationship,several abstract problems on linear transformation are solved concisely by transforming them to their corresponding matrix questions.The mathematical idea of converting complex and abstract concepts to simple and concise objects,as well as several other important mathematical ways of thinking,are emphasized.
