Best ResponseYou've already chosen the best response.0I know that's how this problem should be solved, and I more or less know them, but I still get messed up on some of them. Like this one...

Best ResponseYou've already chosen the best response.0Cool, @oldrin.bataku should be able to explain it to you. I skip a lot of steps when explaining stuff like that.

Best ResponseYou've already chosen the best response.0$$xy''y'+2y=0$$Observe we may rewrite this in standard form:$$y''\frac1xy'+\frac2xy=0$$which has a very apparent singular point at \(x=0\). With a little further attention we can see it's a regular singular point.

Best ResponseYou've already chosen the best response.0The method of Frobenius assumes, then, a solution of the form \(y=\sum\limits_{n=0}^\infty a_nx^{r+n}\) (note our expansion about the singular point).

Best ResponseYou've already chosen the best response.0@oldrin.bataku I'm so lost. Tried to so something and got a mess. you explained the others very well, could you explain this one to if you're still here somewhere?
