Webthe curl of F is zero. The vector field is defined in all R 3, which is simply connected , so F is conservative. We need to find a potential function f ( x, y, z) that satisfies ∇ f = F, i.e., the three conditions ∂ f ∂ x ( x, y, z) = 2 x y z 3 + y e x y ∂ f ∂ y ( x, y, z) = x 2 z 3 + x e x y ∂ f ∂ z ( x, y, z) = 3 x 2 y z 2 + cos z.

WebNov 28, 2014 · Curl is not technically defined that way. In fact, it couldn't be defined that way, because determinants are only defined for ALL scalar components (or ALL vector components, if you want to consider each column to be a vector) but the e ^ i 's are vectors, the ∂ ∂ x i 's are operators, and the V i 's are scalars. – user137731 Nov 28, 2014 at 14:08
