"WebJul 25, 2024 · If \(P\) is a point on the curve, then the best fitting circle will have the same curvature as the curve and will pass through the point \(P\). We will see that the curvature of a circle is a constant \(1/r\), where \(r\) is the radius of the circle. The center of the osculating circle will be on the line containing the normal vector to the circle. " - Derivation of radius of curvature
