The directional derivative in a direction that"s perpendicular to the gradient is basically zero.
垂直于梯度的方向上，方向导数为零。
So the derivative in any direction, tangent to g equals c, should be the directional derivative of f, in any such direction, should be zero.
所以这个与g=c相切的导数，应该是f的方向导数，在这个方向下，应该是等于0的。
So, now, similarly, the directional derivative means, actually, we"ll be slicing our graph by the vertical plane.
类似地，方向导数的意思是，用垂直平面切开图像。

Well, it"s actually the directional derivative in that direction.
它其实是那个方向的方向导数。
And, the slope is going to be the directional derivative in that direction OK, I think that"s as graphicas I can get.
这个斜率就是此方向的方向导数，好了，我想我说的已经尽量图形化了。
