WebIn addition to defining curl and divergence, we look at some physical interpretations of them, and show their relationship to conservative and source-free vector fields. Divergence Locally, the divergence of a vector field F in ℝ 2 ℝ 2 or ℝ 3 ℝ 3 at a particular point P is a measure of the “outflowing-ness” of the vector field at P . WebSal says that in order to represent the vector field as the gradient of a scalar field, the vector field must be conservative. That a vector field is conservative can be tested by obtaining the curl (𝛁⃗⨉F⃗) of the vector field; if it's 0, then the field is conservative.

WebThe vector field F is indeed conservative. Since F is conservative, we know there exists some potential function f so that ∇ f = F. As a first step toward finding f , we observe that the condition ∇ f = F means that ( ∂ f ∂ x, ∂ f ∂ y) = ( F 1, F 2) = ( y cos x + y 2, sin x + 2 x y − 2 y).
