This question gives us a vector field and asks us to sketch it.
00:03
So what's the vector field it gives us? it gives us f is equal to x comma zero.
00:08
So in the y coordinate, it's always going to be zero.
00:11
We're always going to not be going up or down.
00:14
But we depend on our x coordinate.
00:16
So let's draw the plane.
00:18
We have the y direction and then the x direction.
00:21
So we pick a point that's the origin.
00:24
Well, the x value is zero, so we have no vector here.
00:27
We have zero comma zero.
00:28
If we go to 1, then we'll have an x value of 1, so we have 1 comma 0.
00:33
If we go to 2, then we'll have 2 comma 0, so it moves faster...
