Distance Traveled Along a Curved Path
The length of a plane curve can be estimated by dividing the curve into
segments, as in Figure 7-1 5, and approximating the length of the curve segment
by the straight line AB. The length of AB = d m . The distance along
the curve is found by summing the lengths of the segments.

by the length of the straight line segment AB.
