自从复数与复平面上的点建立对应之后 ,复数与图形便结下了不解之缘———一些复数的运算表现出明显的几何意义 .解题中恰当地利用这些复数运算的几何意义 ,便能获得简捷的解法 .在数学竞赛中 ,利用复数运算的几何意义解决的复数问题则更为常见 .本文主要介绍复数运算的几何意 Since complex numbers correspond to points on complex planes, complex numbers and graphs have become inextricably linked. Some complex numbers have obvious geometrical meanings. The geometric meanings of these complex numbers are used appropriately in problem solving. A simple solution can be obtained. In mathematics competition, the complex number problem solved by the use of the complex meaning of complex arithmetic is more common. This paper mainly introduces the geometric meaning of complex arithmetic.
