tangent plane信息详情
切面相切平面
tangent───n.(Tangent)(美、印度)坦根特(人名);n.切线,切面;正切;adj.切线的,相切的;接触的;离题的
plane───vt.刨平;用刨子刨;掠过水面;n.飞机;平面;程度,水平;n.(Plane)人名;(塞、瑞典、法)普拉内;vi.刨;乘飞机旅行;翱翔;adj.平的;平面的
externally tangent───外切的
assailant tangent───攻击切线
tangent line───[数]切线,正切
make plane───制造飞机
ecliptic plane───黄道平面
part plane───零件平面
swordfish plane───旗鱼飞机
It is really the tangent plane.───它确实就是切平面。
That is how we get the tangent plane.───这样我们就得到了切平面。
That's the equation of a tangent plane.───这就是切平面的方程。
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。
