(1) ( α − c) ⋅ ( α − c) = r 2, since α lies on the sphere of radius r centered at c; this is just what equation (1) affirms. If we differentiate (1) with respect to s, the arc-length along α, we obtain. henry christyhenry chubbThe Frenet–Serret formulas mean that this coordinate system is constantly rotating as an observer moves along the curve. Hence, this coordinate system is always non-inertial. The angular momentum of the observer's coordinate system is proportional to the Darboux vector of the frame.
