# By parts ?

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.
