Geometrical Interpretation of the Gradient: Like any vector, the gradient has
magnitude and direction. To determine its geometrical meaning, let's rewrite the
dot product (1 .35) in abstract form: dT = VTd\= \VT\\d\\cos0, (1.37) where 0 is the
The gradient V7" is a vector, so we can take the divergence and curl of it: (1)
Divergence of gradient: V - (VT). (2) Curl of gradient: V x (V7"). The divergence V
- v is a scalar — all we can do is take its gradient: (3) Gradient of divergence: V(V
- v) ...
The scalar potential is not unique — any constant can be added to V with
impunity, since this will not affect its gradient. If the divergence of a vector field (F)
vanishes (everywhere), then F can be expressed as the curl of a vector potential (
