Say you have an arbitrary function f(x,y) and you have the partial derivative fx(adsbygoogle = window.adsbygoogle || []).push({});

How would you go about finding the general form of this integral?

[tex]\int f^{5}(f_{x}+2f_{y})[/tex]

I wanted to treat fx+fy = df, but the constant 2 really messes that up.
