Here we cover four different ways to extend the fundamental theorem of calculus to multiple dimensions. Green's theorem and the 2D divergence theorem do this for two dimensions, then …

If the vector field represents the flow velocity of a moving fluid, then the curl is the circulation density of the fluid. The circulation is defined as the integral of the velocity around a closed curve.

Apr 7, 2018 · I'm studying Calculus, not physics, but was curious how units work when we consider curl over a 2D velocity field. Given $\mathbf{F} = M(x,y)\mathbf{i} + N(x,y)\mathbf{j}$ …

Definition: If $\mathbf{F}(x, y) = P(x,y)\vec{i} + Q(x, y) \vec{j}$ and $\frac{\partial Q}{\partial x}$ and $\frac{\partial P}{\partial y}$ both existence then the Curl of $\mathbf{F}$ is the vector field …

May 26, 2016 · The meaning of positive curl in a fluid flow can sometimes look a bit different from the clear cut rotation-around-a-point examples discussed in previous videos. Courses on Khan …

It explains how the 2D curl is calculated by taking the difference between the partial derivatives of the vector's components with respect to x and y. The script vividly illustrates the physical …

-The 2D curl represents fluid rotation by indicating the tendency of fluid particles to rotate around a point in a counter-clockwise direction. A positive curl indicates counter-clockwise rotation, …
