(of a function,f(x, y, z)) the vector whose components along the axes are the partial derivatives of the function with respect to each variable, and whose direction is that in which the derivative of the function has its maximum value. Usually written: gradf, ∇for ∇f. Comparecurl...

We can interpret this gradient as a vector with the magnitude and direction of the maximum change of the function in space. We can relate the gradient to the differential change in the function: df = (,f/,x) dx + (,f/,y) dy + (,f/,z) dz = ,f , dr = df . Since the del...
Curl said: Okay then prove that grad X Field is equal to the limiting value of the loop integral F*dr divided by area enclosed by the path, as the area approaches zero. When we compute curl we differentiate the vector field using a determinant. How do we know that it gives the same...
The gradient is a fancy word for derivative, or the rate of change of a function. It’s a vector (a direction to move) that Points in the direction of greatest increase of a function (intuition on why) Is zero at a local maximum or local minimum (because there is no single direction...

This paper establishes important properties of the gradient, divergence, curl and Stokes operators in ℝ 3 . They are set in the weighted Sobolev spaces of Hanouzet with finite integer weights ranging from -∞ to +∞. Among the results that we prove are isomorphism properties of the gradient...
