Integrating a Diff. Equation: Seeking Assistance

[skook]

Could someone please point me forwards again.
By integrating the following equation twice...
\frac{1}{x^2}\frac{d}{dy}(x^2 \frac{dx}{dy}) = 0
I tried integrating by parts but came to a sticky end.
many thanks

I'm not sure what you're trying to do but it appears that

x^2\frac{dx}{dy} = C

is a constant and you should be able to integrate that.

Guess I was staring at it too hard. thanks
