Problem: Find the first order behavior of $y'' = \frac{2xy}{x^3 + y^3}, y(0)=1,y'(0)=1$ in the limit $x \rightarrow \infty$. Please place your final solution in a $\boxed{}$ LaTeX Environment. If there are multiple solutions please separate them with a ;.
Solution: $\boxed{y = 6^{1/3} x \ln(x)^{1/3}}$
