$\"\"$

The integral is $\"\"$ .

$\"\"$

Now compare the given integral with the $\"\"$ .

Find $\"\"$ .

Apply formula: $\"\"$

It is convergent because $\"\"$ .

The Comparison Test :

Suppose that $\"\"$ and $\"\"$ are two continuous functions and $\"\"$ on the interval $\"\"$ .

(i) If $\"\"$ is convergent, then $\"\"$ is also convergent.

(ii) If $\"\"$ is divergent, then $\"\"$ is also divergent.

$\"\"$ is also convergent by Comparison Test.

$\"\"$

$\"\"$ is convergent.
