Final answer:
To find the arc length of a curve on an interval, you need to calculate the integral of a specific function over the interval.
Step-by-step explanation:
The arc length (s) of a curve on an interval is calculated using the formula s = √(1 + (dy/dx)^2)dx, where the interval is denoted as [a, b], and dy/dx is the derivative of the function representing the curve. To find the arc length, you need to evaluate the integral of √(1 + (dy/dx)^2)dx over the interval [a, b]. This integral will give you the arc length of the curve.
