WebThe curl of a gradient is zero Let f ( x, y, z) be a scalar-valued function. Then its gradient ∇ f ( x, y, z) = ( ∂ f ∂ x ( x, y, z), ∂ f ∂ y ( x, y, z), ∂ f ∂ z ( x, y, z)) is a vector field, which we denote by F = ∇ f . We can easily calculate that the curl of F is zero. We use the formula for curl F in terms of its components WebI'm stuck on the notation of the 2d curl formula. It takes the partial derivatives of the vector field into account. I believe it says the "partial derivative of the field with respect to x minus the partial derivative of the field with respect to y", but I'm not certain. Since I'm using noise to drive this vector field, I'd like to use finite ...
