directional derivative造句

Well, it's actually the directional derivative in that direction.

And that's basically, yes, that's the directional derivative.

The directional derivative in a direction that's perpendicular to the gradient is basically zero.

And,the slope is going to be the directional derivative in that direction OK, I think that's as graphicas I can get.

You may recall from Part 2 in this series that the directional derivative of the objective function gives the direction in which the objective function grows in a maximization problem.

Let's say the same thing in terms of directional derivatives.
