$\"\"$

\

The curve is $\"\"$ .

\

The domain of the function $\"\"$ is acceptable and the domain of $\"\"$ is $\"\"$ .

\

So domain of the entire function is $\"\"$ .

\

Length of the curve $\"\"$ on the interval $\"\"$ is $\"\"$ .

\

Find $\"\"$ .

\

The function is $\"\"$ .

\

Differentiate the function with respect to $\"\"$ .

\

$\"\"$

\

$\"\"$

\

$\"\"$ .

\

$\"\"$

\

Substitute $\"\"$ , $\"\"$ and $\"\"$ in $\"\"$ .

\

$\"\"$

\

$\"\"$

\

$\"\"$ .

\

$\"\"$

\

Length of the curve $\"\"$ on $\"\"$ is $\"\"$ .
