find div F and curl F for the vector function F(x,y)=i+(x2+y2)j Divergence and Curl of a Vector Function:Let F(x,y)=Pi→+Qj→ be the given vector point function. The curl of the given function is given by CurlF=|i→j→∂P∂x∂Q∂y|. Th...
The divergence of vector point function is scalar quantity and curl of vector point function is vector quantity.Answer and Explanation: Given A vector field {eq}F\left( {x,y,z} \right) = \left( { - 6yz, - 9xz,xy} \right) {/eq}. The vector point function...
The divergence of a vector field is a scalar function. Divergence measures the “outflowing-ness” of a vector field. If vv is the velocity field of a fluid, then the divergence of vv at a point is the outflow of the fluid less the inflow at the point. The curl of a vector field...

The curl measures the tendency of the paddlewheel to rotate. Figure 1. To visualize curl at a point, imagine placing a small paddlewheel into the vector field at a point. Consider the vector fields in Figure 1 from the Divergence learning objective. In part (a), the vector field is ...

Given a vector valued function {eq}\displaystyle \vec{F}(x,y,z) = F_{1}(x,y,z) \vec{i}+F_{2}(x,y,z) \vec{j} + F_{3}(x,y,z) \vec{k} {/eq} The divergence of such a vector is given by: {eq}\displaystyle \nabla \cdot \vec{F}(x,y,z...
The force vector (2) is defined by the field we are in. No derivatives or other changes are necessary -- every point in the field has some force acting on it. So, our formula for circulation is: Remember, velocity is simply the derivative of position (r), so (dr) is a vector givi...
of a vector field A, the vector characteristic of a “rotating component” of field A. The curl is represented by the symbol rot A. It can be interpreted in the following manner: Let A be the velocity field of a fluid flow. At a given point of the flow we place a small wheel with...
