WebVector Analysis. Vector analysis is the study of calculus over vector fields. Operators such as divergence, gradient and curl can be used to analyze the behavior of scalar- and vector-valued multivariate functions. Wolfram Alpha can compute these operators along with others, such as the Laplacian, Jacobian and Hessian. WebThe curl of a vector field →v ∇ × →v measures the rotational motion of the vector field. Take your hand extend your thumb and curl your fingers. If the thumb is the model for the flow of the vector field, then ∇ × →v = 0. If the curling of your fingers is the model for the flow of the vector field then ∇ × →v ≠ 0 WebThe definition of Laplacian operator for either scalar or vector is almost the same. You can see it by noting the vector identity ∇ × ( ∇ × A) = ∇ ( ∇ ⋅ A) − ( ∇ ⋅ ∇) A Plugging it into your definition produces still Δ A = ( ∇ ⋅ ∇) A Share Cite Follow answered Oct 12, 2013 at 1:06 Shuchang 9,682 4 25 44 Add a comment 0 dark web search browser
