The Gradient
The gradient V of a scalar field V is a vector that represents both the
magnitude and the direction of the maximum space rate of increase of V.
The gradient V at any point is directed normal to the constant V

Curl of a Vector
Field
Dr. Rajib Kumar Panigrahi
Curl
The curl of A is an axial (or rotational) vector whose
magnitude is the maximum circulation of A per unit area as
the area tends to zero and whose direction is the normal
direction of the area when th
