Gradient is the derivative of a scalar field. Divergence and Curl are both derivative of a vector field.
1) Are "scalar field" and "vector field" imply it is spatial dependent...ie they are function of any single point in space...ie the value of scalar and vector field is different at every single point in space if it is not a constant field.
2) Does this mean all three ( Gradient, Div, Curl ) are point form?...ie each point give different result.
3) Is "point form" means the function is different at every single individual point in space?
4) In electromagnetics, there are [itex]\nabla'[/itex] that represent operation respect to source point and [itex]\nabla[/itex] represent operation respect to field point of interest. I am confuse with this. Can anyone explain this?I just want to have a clearer understanding of the del operator.
Thanks
