👉 In mathematics, a nonradial curve is one whose tangent line at any point lies outside of the curve. In other words, it's an object that doesn't pass through the center of the circle or ellipse. Nonradial curves can be used to model various geometric shapes and structures in geometry and physics. For example, consider a sphere with radius 1 unit (a nonradial curve). A plane passing through the center of the sphere will intersect it at two points, and these points
