It is just an evaluation problem which looks like this dx/dy = x^2 y^2 / 1+x
dx/dy = x^2 y^2 / 1 + x
The Attempt at a Solution
What i did is cross multiply to get this equation y^2 dy = x^2 / 1+x dx then next line ∫y^2 dy = ∫x^2/1+x dx
y^3/3 = ∫dx + ∫1/x dx after simplifying i get y^3=3x + 3 ln x + C but im not sure if this is the right answer.
