👉 Point rel is a mathematical concept in vector calculus that relates a vector field to its normal and tangent vectors. It was introduced by mathematician Carl Friedrich Gauss, who used it to develop his differential geometry of curves. The point-rel concept states that a curve can be described as a family of points connected by straight lines, where the direction of each line is determined by the slope (gradient) of the vector field at that point. This means that every point on the curve has a unique normal vector pointing
