VectorAnalysis`

Curl

As of Version 9.0, vector analysis functionality is built into the Wolfram Language »

Curl[f]

gives the curl, ∇×f, of the vector field f in the default coordinate system.

Curl[f,coordsys]

gives the curl of f in the coordinate system coordsys.

Details and Options

To use Curl, you first need to load the Vector Analysis Package using Needs["VectorAnalysis`"].
The vector field f should be a 3-element list where each element is a function of the coordinates of the appropriate coordinate system.

Compute the curl of a vector field:

Find the parameter values for which the vector field is irrotational:
