解析 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...反馈 收藏 ...
If w is the nth root of unity with the smallest positive argument, i.e., w= (cis)((2π)n ), show that: (1)the n roots of z^n=1 are 1, w, w^2, w^3, ⋯⋯, w^n (2)1+w+w^2+w^3+⋯⋯+w^(n-1)=0Note: The roots of unity lie on the unit circle, equall...

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 ...
