复数的n次单位根如何理解 nth roots of unity,复数的n次单位根 对于给定n=1,2,3,. 复数的n次单位根z满足等式: z^n = 1 怎
单位根(unit root) 设n 是正整数,当一个数的n 次乘方等于1 时,称此数为n 次“单位根”.在复数范围内,n 次单位根有n 个.例如,1、-1、i、-i 都是4次单位根.确切的说,单位根指模为1的根,一般的x^n=1的n个根可以表示... 解析看不懂?免费查看同类题视频解析查看解答 更多答案(2) ...

The special case of the square root () is denoted . The case is known as the cube root. The quantities for which a general function equals 0 are also called roots, or sometimes zeros. The quantities such that are called the th roots of unity. Rolle proved that any complex number ...
Roots are particularly important in the theory of infinite series, where the root test determines the radius of convergence of a power series. Roots can also be defined for complex numbers, and the complex roots of 1 (the roots of unity) play an important role in higher mathematics. Much ...
