Isn't the first of the theorems mentioned just a definition, namely the definition given in the text above it?

[edit] Geodesic Curvature Unsigned?

Is scalar geodesic curvature the magnitdue of the vector, or the determinant of the projection onto the tangent plane and the tangent vector? I am looking the other things that refer to geodesic curvature and I can not figure out how the citing articles can use it unless it is signed. 149.169.152.14 20:04, 12 January 2007 (UTC)
