WebMay 22, 2024 · The symbol ∇ with the gradient term is introduced as a general vector operator, termed the del operator: ∇ = i x ∂ ∂ x + i y ∂ ∂ y + i z ∂ ∂ z. By itself the del operator is meaningless, but when it premultiplies a scalar function, the gradient operation is defined. We will soon see that the dot and cross products between the ... Web7. Direct computation shows that F satis es the Clairaut’s test. But it’s not a gradient vector eld. Because it’s ow lines are circles, which are closed curves.
