Example Question #781 : Partial Derivatives

Find  of the following function:

Possible Answers:

Correct answer:

Explanation:

To find the given partial derivative of the function, we must treat the other variable(s) as constants. For higher order partial derivatives, we work from left to right for the given variables.

To start, we must find the partial derivative of the function with respect to y:

This derivative was found using the following rules:

Next, we must find the partial derivative of the above function with respect to z:

We used rules above as well as
