(adsbygoogle = window.adsbygoogle || []).push({}); Evaluate partial derivative. chain rule??

I would like to represent the term identified in the image as (term 1)

in terms of those partial derviatives that are known. Unfortunatly I just cant seem to wrap my head around it at the moment.

A prod in the right direction would be greatly appreciated.

It would appear that V^2 is also equal to u^2+w^2..
