The normal vector, often simply called the "normal," to a surface is a vector which is perpendicular to the surface at a given point. When normals are considered on closed surfaces, the inward-pointing normal (pointing towards the interior of the surface) and outward-pointing normal are ...
Vector Normal and Gradient of a Function: A vector is normal to a surface at a point if it is perpendicular to the tangent plane at that point on the surface. This property tells us that a normal vector is perpendicular to any other vector contained in the tangent ...

The unit normal vector to the surface, f(x,y,z)=0 at the point (a,b,c) is a vector obtained by dividing the gradient of f(x,y,z) at the point (a,b,c) by its norm, and it is denoted by n^, that is, n^=∇f(a,b,c)‖∇f(a,b...
