1. Homework Statement
I've attactched an image of the question, I hope this is ok, if not let me know and I'll copy it out onto a post,
3. The Attempt at a Solution
I've done parts (a) and (b) using the total derivative of f ( http://mathworld.wolfram.com/TotalDerivative.html ) but I can't get started on the last part. I've tried differentiating the expressions found in (a) but it doesn't seem to lead anywhere.
A push in the right direction would be appreciated.
Thanks
