WebOne way to get a vector normal to a surface is to generate two vectors tangent to the surface, and then take their cross product. Since the cross product is perpendicular to both vectors, it will be normal to the surface at that point. We’ll assume here that our surface can be expressed as z = f(x,y). WebJan 18, 2015 · The gradient of a function f is the 1-form df. The curl of a 1-form A is the 1-form ⋆ dA. The divergence of a 1-form A is the function ⋆ d ⋆ A. The Laplacian of a function or 1-form ω is − Δω, where Δ = dd † + d † d. The operator Δ is often called the Laplace-Beltrami operator.
