For a function in three-dimensional Cartesian coordinate variables, the gradient is the vector field: As the name implies, the gradient is proportional to and points in the direction of the function's most rapid (positive) change. For a vector field written as a 1 × n row vector, also called a tensor field of order 1, the gradient or covariant derivative is the n × n Jacobian matrix: WebJun 16, 2014 · A × ( B × C) = B ( A ⋅ C) − C ( A ⋅ B) And the product rule. Let ∇ ˙ × ( F ˙ × G) mean "differentiate F only; pretend G is constant here". So the product rule would read. ∇ × ( F × G) = ∇ ˙ × ( F ˙ × G) + ∇ ˙ × ( F × G ˙) Now, apply the BAC-CAB rule. I'll do this for just one term for brevity: ∇ ˙ × ( F ˙ × G ...

The curl of a vector field F, denoted by curl F, or $${\displaystyle \nabla \times \mathbf {F} }$$, or rot F, is an operator that maps C functions in R to C functions in R , and in particular, it maps continuously differentiable functions R → R to continuous functions R → R . It can be defined in several ways, to be … See more In vector calculus, 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 … See more Example 1 The vector field $${\displaystyle \mathbf {F} (x,y,z)=y{\boldsymbol {\hat {\imath }}}-x{\boldsymbol {\hat {\jmath }}}}$$ can be decomposed as See more The vector calculus operations of grad, curl, and div are most easily generalized in the context of differential forms, which involves a number of steps. In short, they correspond to the derivatives of 0-forms, 1-forms, and 2-forms, respectively. The geometric … See more • Helmholtz decomposition • Del in cylindrical and spherical coordinates • Vorticity See more In practice, the two coordinate-free definitions described above are rarely used because in virtually all cases, the curl operator can be applied using some set of curvilinear coordinates, for which simpler representations have been derived. The notation ∇ × F … See more In general curvilinear coordinates (not only in Cartesian coordinates), the curl of a cross product of vector fields v and F can be shown to be See more In the case where the divergence of a vector field V is zero, a vector field W exists such that V = curl(W). This is why the magnetic field, characterized by zero divergence, can be expressed as the curl of a magnetic vector potential. If W is a vector field … See more WebR 1 0 f = 0g.
