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 … WebDec 14, 2024 · The gradient is (dV/dx)i + (dV/dy)j + (dV/dz)k. In this case (dV/dx) = [-GM (-1/2) ( x 2 + y 2 + z 2) ( − 3 / 2) ] [ (2x)]. The y and z components are similar. Adding these three gives the negative of the gradient as: [-GM/ ( r 3 )] [xi + yj + zk] which gives g (as a vector). Or,in polar coordinates: V = -GM r − 1 and the gradient is GM/ r 2.
