# How would you integrate

Say you have an arbitrary function f(x,y) and you have the partial derivative fx

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

$$\int f^{5}(f_{x}+2f_{y})$$

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

with respect to which variable are you integrating? x,y?

Yes... as the integral is written, I'm not sure it means much.
