WebA derivation of the formula to determine the radius of curvature of any curve … WebIn differential geometry, the radius of curvature (Rc), R, is the reciprocal of the curvature. For a curve, it equals the radius of the circular arc which best approximates the curve at that point. For surfaces, the radius of curvature is the radius of a circle that best fits a normal section or combinations thereof.

Curvature can actually be determined through the use of the second derivative. When the second derivative is a positive number, the curvature of the graph is concave up, or in a u-shape. When the second derivative is a negative number, the curvature of the graph is concave down or in an n-shape. greek fashion 110

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.
