The integral is $\"\"$ .

Comparison theorem :

Suppose that $\"\"$ and $\"\"$ are continuous functions with $\"\"$ for $\"\"$ ,

1. If $\"\"$ is convergent, then $\"\"$ is convergent.

2. If $\"\"$ is divergent, then $\"\"$ is also divergent.

Here $\"\"$ and $\"\"$ .

$\"\"$

Since $\"\"$ is a finite value, it is convergent.

Thus, $\"\"$ is convergent.

$\"\"$ is convergent.
