WebObjects of the root_criterion class decide if a given directory is a project root. In mathematics, the root test is a criterion for the convergence (a convergence test) of an infinite series. It depends on the quantity $${\displaystyle \limsup _{n\rightarrow \infty }{\sqrt[{n}]{ a_{n} }},}$$where $${\displaystyle a_{n}}$$ are the terms of the series, and states that the series converges absolutely if this … See more The root test was developed first by Augustin-Louis Cauchy who published it in his textbook Cours d'analyse (1821). Thus, it is sometimes known as the Cauchy root test or Cauchy's radical test. For a series See more Since $${\displaystyle {\sqrt[{-n}]{a_{n}}}=\mathrm {e} ^{-{\frac {1}{n}}\ln a_{n}}}$$, then we have From this, See more • Ratio test • Convergent series See more This test can be used with a power series $${\displaystyle f(z)=\sum _{n=0}^{\infty }c_{n}(z-p)^{n}}$$ where the coefficients cn, and the center p are See more The proof of the convergence of a series Σan is an application of the comparison test. If for all n ≥ N (N some fixed natural number) we have $${\displaystyle {\sqrt[{n}]{ a_{n} }}\leq k<1}$$, then $${\displaystyle a_{n} \leq k^{n}<1}$$. Since the See more

WebIt turns out that there can be no root on the imaginary axis (such that Re(s)=0) in the regular case. Conversely, if the roots are in the left half-plane (LHP), the 14 case must be regular.
