(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

If V=x[tex]^{3}[/tex]f(y/x) show that x[tex]^{2}[/tex]V_{xx}+ 2xyV_{xy}+ y[tex]^{2}[/tex]V_{yy}= 6V

3. The attempt at a solution

i would normally just use the chain rule to differenciate this with respect to x and then so on but the f(y/x) is throwing me. Do i just treat the f like a constant or is it a whole new function which i have to differenciate first?

thanks
