Oh well, I'm weak with these
There's a sin and cos (or a sinh or cosh) floating around there somewhere
You posted the answer to the previous question seconds before I did, so I tried yours

simplified its -y= (-2/x^2) + 3/x ...assuming that y'' is y^2...still working on the other, whats wrong one...my skills need to be refreshed. |
No, it's a "simple" Cauchy-Euler differential equation. y' is the first derivative of y and y'', the second derivative. It should be possible without having to write down a lot of work. It's not that difficult if you've done them before.
Here's the big hint for it: y = x^m
