I don't even know where to start this one. I can do all the other problems in the section, but this one makes no sense

Vector calculus is a branch of mathematics that deals with the differentiation and integration of vector fields. It combines the concepts of multivariable calculus, linear algebra, and geometry to study and analyze the properties of vector fields.
A vector field is a mathematical function that assigns a vector to each point in a given space. This vector represents the direction and magnitude of a physical quantity, such as velocity, force, or electric field, at that point.
Divergence is a measure of how much a vector field is "spreading out" or "converging" at a given point. It is represented by the divergence operator (∇ · F) and is a scalar value. A positive divergence indicates that the vectors are spreading out, while a negative divergence indicates they are converging.
A divergent vector field is a vector field in which the vectors are spreading out from a given point. This means that the divergence at that point is positive. Examples of divergent vector fields include a source, where vectors radiate outwards, and a fluid flow, where particles move away from a center point.
Divergence is an important concept in vector calculus as it helps us understand and analyze the behavior of vector fields. It allows us to determine whether a vector field is converging or diverging at a given point, and can be used to solve a variety of physical and mathematical problems, such as calculating fluid flow rates or finding electric field strengths.
