Convert gradient to normal vector

WebIf v is a tangent vector at x which is tangent to the level set then dxf(v) = 0 since f doesn't change if we go (infinitesimally) in the direction of v. Hence our vector ∇f (aka u in the question) must satisfy ∇f, v = 0. That is, ∇f is normal to the set of tangent vectors at x which are tangent to the level set.
