I have the equations
[tex]\frac{l}{u^{2}} \frac{du}{dx}=constant[/tex]
and
[tex]\frac{1}{u} \frac{dl}{dx}=constant[/tex].
By "eyeball", I can say the solution is
[tex]l \propto x^{n} \ and \ u \propto x^{n-1}[/tex].
I can't see how I could arrive at these solutions 'properly', if you know what I mean
[tex]\frac{l}{u^{2}} \frac{du}{dx}=constant[/tex]
and
[tex]\frac{1}{u} \frac{dl}{dx}=constant[/tex].
