tangent plane

tangent plane什么意思,tangent plane翻译

基本解释

un.: 切面；切线平面
网络: 切平面；切面公差；相切平面

英汉解释

• 切线平面

• 切面

例句

• Say you have a minimum, well, the tangent plane at this point, at the bottom of the graph is going to be horizontal.

  如果你说这是个极小值，那么这点的切平面应该是水平的。

• Well, that means the gradient is actually perpendicular to the tangent plane or to the surface at this point.

  那意味着，梯度向量在这点上，垂直于切平面或者是等值面。

• Well, one way to think about it is in terms of tangent plane approximation.

  我们可以从用切平面逼近的想法来入手。

• And now what this approximation formula here says is that, in fact, the graph of a function is close to the tangent plane.

  这里这个近似式的意思是，函数图象和切平面靠得很近。

• If we were moving on the tangent plane, this would be an actual equality.

  如果我们在切平面上移动，这将会是一个真正的等式。

• That"s the equation of a tangent plane.

  这就是切平面的方程。

• Let"s think about the tangent plane with regard to a function f.

  我们来考虑，关于函数f的一个切平面。

• In fact, when we turn this into an equality, that would mean that we replace f by the tangent plane.

  其实，看这个等式，就是用切平面上的值来近似f的值。

• And, here"s a tangent plane at the given point.

  在这个给定的点有一个切平面。

• We are replacing the graph by its tangent plane.

  我们用函数的切平面来替代它的图像。
