    Yes, we do offer free help, but not 'free answers'... =/

    Do you know how to differentiate an expression with one variable?



    So, you can express the derivative of what you got as:



    You can differentiate the first part?

    For the second part, let me give you an example.



    As you can see, you differentiate the y similar to how you differentiate x, but you just add dy/dx after differentiating.

    For the middle part of your problem, use the product rule.

    If I may. Allow me to show a method I often use for implicit diff.

    Use

    i.e.







    Just a thought if anyone is interested.

    I wasn't sure what you did at first, but when I expanded it, I understood. Interesting method :)

    You only missed a 'y' in the denominator ;)
