Directional derivative

The directional derivative measures the slope of the tangent line in a given direction.  The gradient vector (gold) always points in the direction of the steepest, most positive directional derivative.  We can see this from the directional derivative derivative formula $D_{\vec u}f = \vec u \cdot Df$.
