👉 In mathematics, a "curf" is an object or function that represents a curve in a three-dimensional space. Curves are important in geometry and calculus, as they represent the shape of objects, such as lines, circles, parabolas, and ellipses. A curf can be defined as a set of points, called nodes, that lie on or near the curve. The curve is assumed to be smooth and continuous, meaning there are no abrupt changes in direction or size.
