复数的三角形式在其乘法、除法、乘方和开方运算中显示出极大的优越性,同时在这几种运算的几何意义的解释和应用方面也发挥着代数式无法替代的功能.因此,掌握好三角式对于学好复数至关重要.但对于复数的三角形式初学者往往只注意其所谓的“三角”这种表面形式,而未注意其结构的本质特征,因此时常出现各种错误.笔者认为学习复数的三角形式时应注意以下三点: Complex triangles show great advantages in their multiplications, divisions, squares, and squares. At the same time, they also play an irreplaceable role in the interpretation and application of the geometric meanings of these types of operations. Grasping triangles is very important for learning plural numbers. However, for complex triangle-shaped beginners, they often pay attention only to their so-called “triangular” surface forms without paying attention to the essential features of their structures. Therefore, various errors often occur. The author It is thought that the following three points should be taken into consideration when learning the triangular form of the plural:
