Homework Statement
If V=x[tex]^{3}[/tex]f(y/x) show that x[tex]^{2}[/tex]Vxx + 2xyVxy + y[tex]^{2}[/tex]Vyy = 6V
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
