### Example Question #5 : Divergence

Find , where F is given by the following curve:

**Possible Answers:**

**Correct answer:**

The divergence of a vector is given by

where

So, we take the partial derivative of each component of our vector with respect to x, y, and z respectively and add them together:

The derivatives were found using the following rules:

, ,

### Example Question #6 : Divergence

Find where F is given by

**Possible Answers:**

**Correct answer:**

The divergence of a curve is given by

where

Taking the dot product of the gradient and the curve, we end up summing the respective partial derivatives (for example, the x coordinate's partial derivative with respect to x is found).

The partial derivatives are:

The following rules were used to find the derivatives:
