math.stmarys-ca.edulength of the circumference of the great circle will equal 2ˇrwhere ris the length of the radius of the sphere. This is relevant because it enables us to calculate the length of a circular segment by considering the relation between the inner angle and the radius of the sphere. Therefore, for any sphere and any angle, the length of one arc ...

13.3 Arc Length and Curvature - United States Naval …
www.usna.eduThe Arc Length Function If a curve r (t) is already given in terms of a parameter t and s (t) is the arc length function given by Equation 6, then we may be able to solve for t as a function of s: t = t (s). Then the curve can be reparametrized in terms of s by substituting for t: r = r(t(s)). Thus, if s = 3 for instance, r(t(3)) is the ...
