tangent plane中文翻譯:
切面相切平面
tangent───n.(Tangent)(美、印度)坦根特(人名);n.切線,切面;正切;adj.切線的,相切的;接觸的;離題的
plane───vt.刨平;用刨子刨;掠過水面;n.飛機;平面;程度,水平;n.(Plane)人名;(塞、瑞典、法)普拉內;vi.刨;乘飛機旅行;翱翔;adj.平的;平面的
externally tangent───外切的
assailant tangent───攻擊切線
tangent line───[數]切線,正切
make plane───制造飛機
ecliptic plane───黃道平面
part plane───零件平面
swordfish plane───旗魚飛機
It is really the tangent plane.───它確實就是切平面。
That is how we get the tangent plane.───這樣我們就得到了切平面。
That's the equation of a tangent plane.───這就是切平面的方程。
Say you have a minimum, well, the tangent plane at this point, at the bottom of the graph is going to be horizontal.───如果你說這是個極小值,那么這點的切平面應該是水平的。
Well, that means the gradient is actually perpendicular to the tangent plane or to the surface at this point.───那意味著,梯度向量在這點上,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.───我們可以從用切平面逼近的想法來入手。
And now what this approximation formula here says is that, in fact, the graph of a function is close to the tangent plane.───這里這個近似式的意思是,函數圖象和切平面靠得很近。
If we were moving on the tangent plane, this would be an actual equality.───如果我們在切平面上移動,這將會是一個真正的等式。
