Step 1:

\

The integral is $\"\"$ .

\

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

\

Consider $\"\"$ and $\"\"$ .

\

$\"\"$

\

Substitute the values of $\"\"$ in $\"\"$ .

\

$\"\"$

\

Step 2:

\

Now solve for $\"\"$ .

\

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

\

Consider $\"\"$ and $\"\"$ .

\

$\"\"$

\

Substitute the values of $\"\"$ in $\"\"$ .

\

$\"\"$

\

$\"\"$ .

\

Step 3:

\

Substitute $\"\"$ in the integral expression of $\"\"$ .

\

$\"\"$

\

Add $\"\"$ to each side.

\

$\"\"$

\

Solution :

\

$\"\"$ .
