What is the Nth root of unity? Given a positive integer n, a complex number z is called an nth root of unity ifzn = 1. In other words, z is a root of the polynomial Xn − 1. ... considered as points in the complex plane, are vertices of a regular n-gon inscribed in the ...
Roots of a Quadratic Equation In algebra, any equation that can be written or rearranged in the following form:ax2+bx+c=0is called the quadratic equation. wherexis the unknown variable anda(≠0),b,care the known real constants. Due to the second degree, a quadratic equation has two roo...
High-speed stereomicroscopic measurements of cilia motion show that during the power stroke, the entire cilium—from the root to the distal point—remains virtually in a plane in a straight and taut posture4. The return stroke, on the other hand, is a continuously deforming, three-dimensional ...
