摘要
n次单位根不仅在复数的开方运算中有奠基作用 ,而且与初等代数的其它内容有十分密切的联系 ,特别是运用n次单位根解决有关三角数列求和与积及有关二项式定理问题思维具有创新性 ,而且通过运用n次单位根的概念与性质解决这些初等代数问题 ,为后继学习级数、复变函数 ,从知识。
The n th root lays a foundation not only to extract the root of the complex number but also to get in touch with the contexts of the primary algebra,especially that it is much easier and innovative to solve the problems of triangle sequence and binomial.The method is unique,simple and concise.Using it,we can improve and enlarge the ways to deal with the continuous studies of the progression and function of complex variable.
