Chapter 39: Exercise 3.2
39.3.2 For the following graphs of vector fields, determine whether the divergence is positive, negative or zero.
Remember: div(v) represents the "outward flux density" of v at a given point.
1.1 Drag the point around and observe the behaviour of the vectors around the box
1.2 Based on your observation
Is the divergence of this vector field positive, negative or zero?
2.1 Drag the point around and observe the behaviour of the vectors around the box
2.2 Based on your observation
Is the divergence of this vector field positive, negative or zero?
3.1 Drag the point around and observe the behaviour of the vectors around the box
3.2 Based on your observation
Is the divergence of this vector field positive, negative or zero?
