Given a vector field(adsbygoogle = window.adsbygoogle || []).push({}); f, I can compute the rotational tendency in the directionn(∇×f·n), the translational tendency in the directiont(∇f·t) and the divergence (∇·f) too. So, given a scalar field f, why I can computethe directional derivative (translational tendency (only∇f·t)) in the wanted direction?
