“directional derivative”造句，怎麼用directional derivative造句

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.

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

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

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

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

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