The curve is $\"\"$ and $\"\"$ .

Graph the curve $\"\"$ and estimate the arc length of the curve under the limits $\"\"$ .

$\"\"$

Observe the graph:

Arc length of the curve under the limits $\"\"$ is $\"\"$ .

$\"\"$

Consider the curve $\"\"$ and $\"\"$ .

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

$\"\"$ .

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

$\"\"$ .

Find the length of the curve $\"\"$ on the interval $\"\"$ .
