👉 In mathematics, an "orblike" is a type of curve or surface that is similar to a sphere but has two additional features:
1.
Two points on the curve
- The curve is defined by two points on its surface.
2.
The curvature of the surface at these points
- At each point on the curve, the curvature (or tangent) vector changes from being zero at infinity (the limit as radius approaches zero) to becoming negative at that point.
