1、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。
2、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。
3、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。
4、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。
5、That's the equation of a tangent plane.───这就是切平面的方程。
6、That is how we get the tangent plane.───这样我们就得到了切平面。
7、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。
8、It is really the tangent plane.───它确实就是切平面。
