The integral Test :

If $\"\"$ is positive, continous, and decreasing for $\"\"$ and $\"\"$ then $\"\"$ and $\"\"$ either converge or both diverge.

The integral series is $\"\"$ .

Let the function be $\"\"$ .

$\"\"$ is positive, continuous and decreasing for $\"\"$ .

Integral Test is applicable for the series.
