Find the divergence of the vector field:

Possible Answers:

Correct answer:

Explanation:

The divergence of the vector field 

where 

In taking the dot product, we get the sum of the respective partial derivatives of the vector field.

The partial derivatives are

Example Question #62 : Line Integrals

Find the divergence of the following vector field:

Possible Answers:

Correct answer:

Explanation:

The divergence of a vector field is given by

where 

When we take the dot product of the gradient with the vector field, we get the sum of the respective partial derivatives of the vector field.

To find the given partial derivative of the function, we must treat the other variable(s) as constants.

The partial derivatives are
