Consider the given vector field. f(x, y, z) = cos(xz)j − cos(xy)k (a) find the curl of the vector field

∇ × F = [xsin(xy)+xsin(xz)]i - ysin(xy)j - zsin(xz)k

Step-by-step explanation:

Given the vector field,

f(x, y, z) = cos(xz)j − cos(xy)k

Curl is represented as ∇×

Curl of the field F given will be expressed as ∇ × F

The symbol ∇ known as nabla is a 3-dimensional vector expressed as

∇ = (δ/δx)i + (δ/δy)j + (δ/δz)k

∇ × F = {(δ/δx)i + (δ/δy)j + (δ/δz)k}× 0i + cos(xz)j − cos(xy)k

Curl of the function can be gotten by finding the cross product as shown in the attachment.

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's

Idrk but i think u should figure out the n dia n then the units it will make it way more easier
