数形结合是一种重要的解题方法,它通过“数”与“形”之间的数学信息转换,使一些初看很难或很繁的数学问题变得容易和简单.由于复数的多种表示形式都有确定的几何意义,因此对于复数问题,正确读懂符号
The combination of number and shape is an important problem solving method. It transforms mathematics information between “number” and “shape” to make it easier and simpler for some math problems that are difficult to see or very complex at first glance. Since multiple representations of complex numbers have a definite geometric meaning, the correct reading of signs for complex numbers
