WebThe gradient of a function is defined to be a vector field. Generally, the gradient of a function can be found by applying the vector operator to the scalar function. (∇f (x, y)). … WebThe gradient is always one dimension smaller than the original function. So for f (x,y), which is 3D (or in R3) the gradient will be 2D, so it is standard to say that the vectors are on the xy plane, which is what we graph in in R2. These …
