This radius changes as we move along the curve. ... The curvature of a given curve at a particular point is the curvature of the approximating circle at that point.

Answer 2

The radius of curvature of the curve at a particular point is defined as the radius of the approximating circle. This radius changes as we move along the curve. The curvature of a given curve at a particular point is the curvature of the approximating circle at that point.
