You can find formula for each property of horizontal curves. In this section, we use definite integrals to find the arc length of a curve. on the interval a t b a t b. A circle is 360 all the way around; therefore, if you divide an arc's degree measure by 360, you find the fraction of the circle's circumference that the arc makes up.Then, if you multiply the length all the way around the circle (the circle's circumference) by that fraction, you get the length along the arc. Example 2: Parametric. However, for calculating arc length we have a more stringent requirement for f (x). As n increases, our line segments get shorter and shorter, giving us a more accurate approximation of the length of the curve.
