Web2 Let F ( x, y, z) = y i ^ + x j ^ + z 2 k ^ be a vector field. Determine if its conservative, and find a potential if it is. Attempt at solution: We have that ∂ F 1 ∂ y = 1 = ∂ F 2 ∂ x, ∂ F 1 ∂ z = 0 = ∂ F 3 ∂ x, ∂ F 2 ∂ z = 0 = ∂ F 3 ∂ y, so the potential might exist. Now we need to find a function f such that ∇ f = F.
