Missing: represents | Show results with:represents

The curl of a vector field, denoted curl(F) or del xF (the notation used in this work), is defined as the vector field having magnitude equal to the maximum "circulation" at each point and to be oriented perpendicularly to this plane of circulation for each point. More precisely, the magnitude of del xF is the limiting value of circulation per unit area. Written explicitly, (del xF)·n^^=lim_(A->0)(∮_CF·ds)/A, (1) where the right side is a line integral around...

The divergence and curl can now be defined in terms of this same odd vector ∇ by using the cross product and dot product. The divergence of a vector field F=⟨ ...

Divergence and curl are two measurements of vector fields that are very useful in a variety of applications. Both are most easily understood by thinking of the vector field as representing a flow of a liquid or gas; that is, each vector in the vector field should be interpreted as a velocity vector. Roughly speaking, divergence measures the tendency of the fluid to collect or disperse at a point, and curl measures the tendency of the fluid to swirl around the point. Divergence is a scalar, that is, a single number, while curl is itself a vector. The magnitude of the curl measures how much the fluid is swirling, the direction indicates the axis around which it tends to swirl. These ideas are somewhat subtle in practice, and are beyond the scope of this course. You can find additional information on the web, for example at

The curl of a vector field A, denoted by curl A or ∇ x A, is a vector whose magnitude is the maximum net circulation of A per unit area as the area tends to zero and whose direction is the normal direction of the area when the area is oriented to make the net circulation maximum!. In Cartesian In Cylindrical In Spherical Given a vector field F(x, y, z) = Pi + Qj + Rk in space. The curl of F is the new vector field This can be remembered by writing the curl as a "determinant" Theorem: Let F be a three dimensional differentiable vector field with continuous partial derivatives. Then Curl F = 0, if and only if F is conservative. Example 1: Determine if the vector field F = yz2i + (xz2 + 2) j + (2xyz - 1) k is conservative. Solution: Therefore the given vector field F is conservative. Example 2: Find the curl of F(x, y, z) = 3x2i + 2zj – xk. Solution: Example 3: What is the curl of the vector field F = (x + y + z, x − y – z, x2 + y2 + z2)? Solution: Example 4: Find the curl of F = (x2 – y)i + 4zj + x2k. Solution:
