    Define The Function, and partial derivative
    Not sure why I'm blanking on this. So far I haven't been having any problems with partial derivatives. And I know the first part is probably easy, and I feel silly for tripping up on it.

    Define the function



    Compute

    and using the definitions of and .

    As I mentioned, I understand the method of applying the partial derivatives, but I am hung up on the definition portion.

    I believe that the approach I would take is the following...

    Partially differentiate with respect to x,


    But then I must not be remembering something when finding the derivative when the function is zero... I might get it when I take a break and come back to it, but in the mean time if someone has something that can at least jog my memory, I would appreciate it.

    Once I find the partial derivatives, I will have no problem calculating and .
