Step 1:

\

The functions are $\"\"$ and $\"\"$

\

$\"\"$

\

Differentiate on each side with respect to $\"image\"$ .

\

$\"\"$

\

Apply Quotient rule in derivatives $\"\"$ .

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

Step 2:

\

$\"\"$

\

Differentiate on each side with respect to $\"image\"$ .

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

Therefore, $\"\"$

\

Step 3:

\

Relation between $\"\"$ and $\"\"$ .

\

If $\"\"$ then $\"\"$ , where $\"\"$ is a constant.

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$ .

\

Solution:

\

$\"\"$ .
