Hi guys i have that (dy/dx)=(y/2x)-(xy)^3

i calculated that the general solution is y=ħsqrt(1/{[(2x^4)/5]+[C/x]})

i used the substitution z=1/y^2

could someone tell me if i got the right solution please?

It is difficult to read what you have, but if it is equivalent to

where , then you are Okey-dokey(Nod)

EDIT: hey, looks like me and big Dan are in the same arena, so I reckon that is it.:)
