The gradient vector | Multivariable calculus (article) | Khan Academy
WEBIn the case of scalar-valued multivariable functions, meaning those with a multidimensional input but a one-dimensional output, the answer is the gradient. The gradient of a function f , denoted as ∇ f , is the collection of all its partial derivatives into a vector. This is most easily understood with an example.
