The total curvature of the portion of a smooth curve that runs from sequalss 0 to s 1 greater than s 0 can be found by integrating kappa from s 0 to s1. If the curve has some other parameter, say t, then the total curvature is Upper K equals Integral from s 0 to s 1 kappa ds equals Integral from t 0 to t 1 kappa StartFraction ds Over dt EndFraction dt equals Integral from t 0 to t 1 kappa StartAbsoluteValue Bold v EndAbsoluteValue dt , where t0 and t1 correspond to s 0 and s1. a.
