I am looking for the general solution the the following equation:
$\frac{d}{dx}(x^n du/dx) + x^nu=o$, $n=1,2,3,.....$
I changed it to $\frac{d^2u}{dx^2}$ + $\frac{n}{x} \frac{du}{dx} + u = 0$
I think it is supposed to become a bessel equation, but the format doesn't quite look like one.
I am not sure how to proceed.
Please help!
