What is the Integral Test for Convergence of an Infinite Series?

1 Answer

Oct 16, 2014

Integral Test

If $f$ $f$ is a function such that $f (n) = a_{n}$ $f(n)=a_n$ , then

$\infty \sum n = 1 a_{n}$ $sum_{n=1}^inftya_n$ and $\int_{1}^{\infty} f (x) d x$ $int_1^infty f(x)dx$ converge or diverge together.

I hope that this was helpful.
