WebThe vector derivative of a scalar fieldf{\displaystyle f}is called the gradient, and it can be represented as: gradf=∂f∂xe→x+∂f∂ye→y+∂f∂ze→z=∇f{\displaystyle \operatorname {grad} f={\partial f \over \partial x}{\vec {e}}_{x}+{\partial f \over \partial y}{\vec {e}}_{y}+{\partial f \over \partial z}{\vec {e}}_{z}=\nabla f} WebThe gradient of a function f f, denoted as \nabla f ∇f, is the collection of all its partial derivatives into a vector. This is most easily understood with an example. Example 1: Two dimensions If f (x, y) = x^2 - xy f (x,y) = x2 …
