Tangential Curvature: Tangential curvature measures how much a curve deviates from being a straight line when viewed in terms of its tangent line at a specific point.
Center of Curvature: The center of curvature is the center of the circle that best approximates a curve at any given point, representing where the curve would continue if it were part of a larger circle.
Radius of Curvature: The radius of curvature is the distance between the center of curvature and any given point on a curve, indicating how sharply or gradually it bends at that particular location.
