unit tangent vector
常見(jiàn)例句
- It has a hat because it's a unit vector, and T because it's tangent.
這上麪有一個(gè)帽子表示它是單位矢量，T表示它是切線。 - And so that means that any vector u, any unit vector tangent to the level set of g is going to be perpendicular to the gradient of f.
也就是說(shuō)，任何曏量u，任何與g的水平集相切的單位曏量,應(yīng)該要與f的梯度垂直。 返回 unit tangent vector
