WebThis theorem, like the Fundamental Theorem of Calculus, says roughly that if we integrate a “derivative-like function” (f 2 or'f) the result depends only on the values of the original function (f) at the endpoints. If a vector fieldFis the gradient of a function,F='f, we say thatFis aconserva- tive vector field. WebJun 11, 2012 · It depends on how you define the gradient operator. In geometric calculus, we have the identity ∇ A = ∇ ⋅ A + ∇ ∧ A, where A is a multivector field. A vector field is a specific type of multivector field, so this same formula works for v → ( x, y, z) as well. So we get ∇ v → = ∇ ⋅ v → + ∇ ∧ v →. how to report job search to centrelink
