Webconverge absolutely, converge conditionally, or diverge? Answer: Notice that lim n→∞ cos 1 n = lim x→∞ cos 1 x = cos lim x→∞ 1 x = cos(0) = 1 since cosine is a continuous function. Therefore, the terms (−1)n cos 1 n are not going to zero, so the Divergence Test says that the series diverges. 8. Determine the radius of convergence ...

What do convergence and divergence mean? And why do they …

WebP>1 you're going to converge. And if zero is less than P is less than or equal to one, you are going to diverge. And those are then the exact, cause this, our p-Series converges if and only if, this integral converges. And so these exact same constraints apply to our original p-Series. WebThe divergence test is a conditional if-then statement. If the antecedent of the divergence test fails (i.e. the sequence does converge to zero) then the series may or may not converge. For example, Σ1/n is the famous harmonic series which diverges but Σ1/ (n^2) converges by the p-series test (it converges to (pi^2)/6 for any curious minds). section plan of residential building
