我们知道在复平面内相同的向量表示相同的复数 ,因此当复数对应的向量平移后它对所应的复数不变 ,但是在平时的教学中许多学生对此未给予足够的重视而常常犯一些错误 ,其主要原因是没有弄清楚复数对应的点的平移与复数对应的向量平移有何区别 ,试比较下面两个问题 :例 1　设复 We know that the same vector in the complex plane represents the same complex number, so when the vector corresponding to a complex number translates it does not change for the applicable complex number, but in the usual teaching many students do not pay enough attention to this and often make some The main reason for the error is that it is not clear what the difference between the translation of a complex point corresponds to the translation of a complex number, and the following two problems are compared: Example 1
