Hi All,(adsbygoogle = window.adsbygoogle || []).push({});

I was looking for the general solution of an equation as y(x)'' = f (y), and found the attached document on the web.

It presents the solution in a way which I am not sure I understand. I tried to look at the trivila example y'' = - y, solution y = sin (x), but I am struggling in obtaining this result with the provided solution.

If anybody could help, I would be the most obliged.

All the Best
