Could I do the Product Rule:

d/dx [ (1/y) dy/dx) ] = (1/y) d^2 y / dx^2 - (1/y^2) dy/dx ?

It's EXTREMELY easy to use. So easy that all I needed to do was copy and paste straight from your post. The great thing is that for most problems, you can even click "Show Steps" next to the answer and it'll walk you through the problem. For this problem, you would use the quotient rule. (I'm assuming Y is a function of X... if it's not, then I don't think this solution is correct).
