How would you integrate

  1. Mar 28, 2009 #1
    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?

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

    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.
