"WebFor a second order tensor field , we can define the curl as. where is an arbitrary constant vector. Substituting into the definition, we have. Since is constant, we may write. where is a scalar. Hence, Since the curl of the gradient of a scalar field is zero (recall potential theory), we have. Hence, " - Curl of gradient index notation

WebThe rules of index notation: (1) Any index may appear once or twice in any term in an equation (2) A index that appears just once is called a free index. The free indices … 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:

WebThe gradient at x = (5, 3) is ∇f(x, y) = (4x, 2y) = (20, 6) Therefore, at x = (5, 3), f is increasing at the rate of 20 along the x axis, and at the rate of 6 along the y axis. 20i + 6j also corresponds to the direction in the x, y plane along which f will increase the most quickly. Gradients of vectors can also be computed.

WebThe equation for each component (curl F)k can be obtained by exchanging each occurrence of a subscript 1, 2, 3 in cyclic permutation: 1 → 2, 2 → 3, and 3 → 1 (where the subscripts represent the relevant indices). If (x1, x2, x3) are the Cartesian coordinates and (u1, u2, u3) are the orthogonal coordinates, then

WebThe proofs of these are straightforward using su x or ‘x y z’ notation and follow from the fact that div and curl are linear operations. 15. 2.
