I am working on a paper that provides the following formula for computing radius of curvature at a point on a surface.(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\frac{1}{\rho_c}=\frac{\partial G/\partial S}{2\sqrt{E}G}[/tex]

where [tex]E[/tex],[tex]G[/tex] are first fundamental coefficients and [tex]S[/tex] is the arc length parameter.

Can any one please tell me the name of the curvature the above mentioned formula computes.
