Best ResponseYou've already chosen the best response.0Try separating variables:\[\frac{ dy }{ dx }=(y4)^2 \rightarrow \frac{ dy }{ (y4)^2 }=dx \]\[\int\limits_{}^{}\frac{ dy }{ (y4)^2 }=\int\limits_{}^{}dx +C\]\[\frac{ 1}{ y4 }=x+C\]Solve for y:\[\frac{ 1 }{ y4 }=Cx\]\[y4=\frac{ 1 }{ Cx }\]\[y=\frac{ 1 }{ Cx }+4\]Where C is a real constant.

Best ResponseYou've already chosen the best response.0If you really want to rewrite it as \[x+f(y)=C\]in my calculation above, just before "solve for y" you could also write it as:\[x+\frac{ 1 }{ y4 }=C\]This means:\[f(y)=\frac{ 1 }{ y4 }\] In my view this is not an answer yet, because it is possible to get y as function of x, as you can see in the end of my calculation.
