\[(x^2+1)y''-xy'+y=0\] do we do a couchy?

I don't think I've encountered a non-homogeneous one.

The cauchy statement doesn't ring a bell with me, sorry.

Make sure to have a backup of what you're typing just in case since in like 3 min, the site is reloading.

the laplace transform is a continuous analog of a power series ... so im wonder ing if that applies here

Actually, this time I really feel like I've done it right but something is wrong. The problem is very likely a minor mistake that caused everything else following it to be wrong. http://f.imgtmp.com/atw39.jpg A != 9 which is what I get. I didn't write it in my work but it's a direct implication of the last thing I wrote.

Lol to my handwriting. It takes sooo much time for me to write nicely and my hand hurts. It's okay if you forgot how to do this but, I'll try to jog your memory just in case: 1) Summations need same indices. 2) I need a recurrence relation. 3) Use that recurrence relation to find the future coefficients if given the initial coefficient a_0. (assuming I'm correct).

:) theres not much to jog. i was trying to decipher the content i found online but cant concentrate enough to figure it out.

Oh, alright. Thanks anyways. I have to go to class but if someone else sees what my mistake is please tell me. It would allow me to go to bed early tonight :)
