$\"\"$

\

The integral is $\"\"$ .

\

$\"\"$ .

\

If $\"\"$ is continuous on the interval $\"\"$ then $\"\"$ is convergent.

\

$\"\"$ .

\

Solve the integral by using integration by parts of integration.

\

Apply integration by parts formula $\"\"$ .

\

$\"\"$

\

Apply derivative on each side with respect to $\"\"$ .

\

$\"\"$

\

$\"\"$ .

\

Consider $\"\"$ .

\

Apply integral on each side.

\

$\"\"$

\

$\"\"$ .

\

Substitute corresponding values in $\"\"$ .

\

$\"\"$

\

$\"\"$

\

Again apply integration by parts.

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

Apply the limits.

$\"\"$

\

$\"\"$

\

Therefore, the integral $\"\"$ is converges to $\"\"$ .

\

$\"\"$

\

The improper integral $\"\"$ is converges to $\"\"$ .
