I need help on solving the nonlinear equation: $x^3y''(x)-y(x)y'(x)=0$. Mathematica simply repeats the above equation in the output.


  • $\begingroup$ Maple performs a complicated expression which is too long to be cited here. $\endgroup$ – user64494 Jan 30 '19 at 18:10

    $\begingroup$ In the book by Micheal Greenberg, the solution to this equation is y1=1 and y2=x^2; yet their linear combination 4+3x^2 is not. This is under the section: Superposition of Solutions for Homogeneous Equation (General Solution). $\endgroup$ – Vikalp Luthra Jan 30 '19 at 18:11
