pr. n 次方根:take the nth root of x :取 x 的n 次方根 e.g. An n th root of a number x is a number y that when raised to the nth power equals x . nth roots of unity are e^{\frac{2k\pi i}{n}}=\cos\left(\frac{2k\pi}{n}\right)+i\sin\left(\frac{2k\pi}{n}\...
If 1,z1,z2,z3,...,z(n-1) be the n, nth roots of unity and omega be a non-real complex cube root of unity, then prod (r=1)^(n-1) (omega-zr) can be equal t
In summary, the conversation discusses finding the sum of a series involving nth roots of unity and the use of complete induction and calculus to solve it. The relevant equation is (1-x)(1+x+...+xn-1) = 1 - xn and the hint is to differentiate x+x^2+...+x^n. ...

An algorithm for computing the Nth roots of unity in bit-reversed order Many versions of the fast Fourier transform require that the user provide a table of the Nth roots of unity arranged in bit-reversed order. An algorithm fo... Keys,R. - 《IEEE Transactions on Acoustics Speech & Signal...
where {eq}\omega {/eq} is any of the {eq}n^{th} {/eq} roots of unity. nth Roots of Unity: An {eq}n^{\rm th} {/eq} root of unity is any complex number that is a solution of {eq}x^n-1=0 {/eq}. We will frequently use the identity that...

A p-modular character of G is called “liftable” if it is the restriction of an ordinary character of G to the p-regular elements. An ordinary irreducible character of G is called p-rational if its values lie in (ω) for some nth root of unity ω with p not dividing n....
. Models that fit the data require a thermal inversion, molecular dissociation as predicted by chemical equilibrium, a solar heavy-element abundance (‘metallicity’,M/H=1.03−0.51+1.11times solar) and a carbon-to-oxygen (C/O) ratio less than unity. The data also yield a dayside brightness...
