The gradient of a scalar field is a vector field and whose magnitude is the rate of change and which points in the direction of the greatest rate of increase of the scalar field. If the vector is resolved, its components represent the rate of change of the scalar field with respect to each directional component. Hence for a two-dimensional scalar field ∅ (x,y).
And for a three-dimensional scalar field ∅(x, y, z)
The gradient of a scalar field is the derivative of f in each direction. Note that the gradient of a scalar field is a vector field. An alternative notation is to use thedel or nabla operator, ∇f = grad f.
For a three dimensional scalar, its gradient is given by:
Gradient is a vector that represents both the magnitude and the direction of the maximum space rate of increase of a scalar.
dV = (∇V) ∙ dl, where dl = ai ∙ dl
