### Example Question #67 : Line Integrals

Find the divergence of the vector field:

Explanation:

The divergence of a vector field is given by

, where

When we take the dot product of the gradient and the vector field, we get the sum of the respective partial derivatives. To find the given partial derivative of the function, we must treat the other variable(s) as constants.

The partial derivatives are
