The gradient (or gradient vector field) of a scalar function f(x1, x2, x3, …, xn) is denoted ∇f or ∇→f where ∇ (nabla) denotes the vector differential operator, del. The notation grad f is also commonly used to represent the gradient. The gradient of f is defined as the unique vector field whose dot product with any vector v at each point x is the directional derivative of f along v. That is, where the right-side hand is the directional derivative and there are many ways to represent it. F… WebThe curl of a vector field F, denoted by curl F, or , or rot F, is an operator that maps C k functions in R 3 to C k−1 functions in R 3, and in particular, it maps continuously differentiable functions R 3 → R 3 to continuous functions R 3 → R 3.It can be defined in several ways, to be mentioned below: One way to define the curl of a vector field at a … photo cleaner for windows

Well, just to complete the above: grad (1/r) = (d/dx xhat + d/dy yhat +d/dz zhat) (1/r) = -x/r^3 xhat -y/r^3 yhat -z/r^3 zhat. = - (x,y,z)/r^3=-rhat/r^2. apologies for being too lazy to latex this.
