This applet is designed to build intuition about divergence and curl of a vector field.
- The applet has a control window and Vector Field window.
- The Vector Field window shows the the vector field V, and a red
hot spot P0 that can be dragged. The divergence at P0 is shown by
a horizontal green bar. The curl at P0 is shown by a vertical
- The control panel lets you define the vector field V=(p,q).
It gives readouts for the value of P0 along with V, and its
divergence and curl, all evaluated at P0.
- The control panel lets you set the viewing window along with the density and scaling factor of the vector field.
