Any approximate radius of a circle at any point is called the radius of curvature . As we move further to the curve, the radius of the curvature alters or modifies. The radius of curvature formula is denoted as 'R'. The radius of curvature is not a real shape or figure rather it's an imaginary circle. Let us learn the radius of curvature formula with a few solved examples. The radius of curvature, which is the inverse of the curvature, conceptualises an imaginary circle rather than an actual shape . This radius pertains to the rough circle at a particular location and is symbolically expressed as ' R R ' using the length of the curvature vector. The radius of curvature is the radius of an approximating circle passing through points on the curve.
