Curl of gradient of any scalar function is

WebYes, curl is a 3-D concept, and this 2-D formula is a simplification of the 3-D formula. In this case, it would be 0i + 0j + (∂Q/∂x - ∂P/∂y)k. Imagine a vector pointing straight up or down, parallel to the z-axis. That vector is describing the curl. Or, again, in the 2-D case, you can think of curl as a scalar value. WebDec 9, 2024 · The curl is a vector operator that describes the infinitesimal circulation of a vector field in three-dimensional Euclidean space. The curl at a point in the field is represented by a vector whose length and direction denote the magnitude and axis of the maximum circulation. how can you take the partial derivative of a vector?
