Signed curvature function
Webextend to functions kX and k'B defined on V. Note that changing the orientation of a curve changes both the sign of the curvature function and the direction of the arclength derivative. It follows that while the functions kA and kB are local functions, defined only up to sign, the functions kX and k'B are actually well-defined functions on all ...
