大家知道,复数z与复平面上的点Z(为方便起见,以下不妨仍用记号z表示)以及与向量是一一对应的,从近世代数“同构”的角度看,三者仅是外衣不同而已,实际上它们可看作不加区别的一回事。由此利用向量解复数题, As we all know, the complex z and the point Z in the complex plane (for convenience, the following may be denoted by the symbol z) and the vector are in one-to-one correspondence. From the perspective of the “isomorphism” of modern algebra, the three are only coats. Different, in fact, they can be seen as indiscriminate. This uses vectors to solve complex problems.
