tried that, no implicit solution,,,

I did, but substituting for trial solutions does not deal to cancelling x, for example y=x^m, you will have x left,,

ahh, just checked the cauchy-euler equation, and from what i understood it does not apply in this case! as the x is in the denominator and only in the second term!

Yes w is a constant! thank you VERY much Dustinsfl! I am now reading about the Cauchy-euler equations and how to solve them! very appreciated! :)

Thank Chestermiller! The thing is that the questions asks at which density the approximation breaks and consequently at what height, i was thinking maybe that would happen at the stratosphere, as the temperature starts to increase in their due to the absorption of UV, so above 9km!

I am having a problem finding the solution for this eq: y''(x)+(2/x)y'(x)+(w^2)y(x)=0 I couldn't find examples in the textbook that goes on a similar line, and have been searching the internet as well, but no use. I am thinking of using substitution v=y' but not sure how to do that in the...

I am modelling the atmosphere as a perfect, static gas subject to uniform gravity, assuming ideal gas equation, the density is found to follow: p=A*exp(-z/H) where A is a const, z is the heigh, and L is the scale height. I want to know when this approximation breaks down! at what density? i am...

no body wants to help even with a suggestion! :(

Dear All, I am having a problem finding the solution for this eq: y''(x)+(2/x)y'(x)+(w^2)y(x)=0 I know it is quite elementary! any pointers will be much appreciated! thanks

I want to present the subject as a new solution to the security problems. it is for my electric engineering degree, so it is more desirable to get into the communications details and the systems specifications more. thank you for your time. and sorry for any headaches caused by lack of...

I apologize for the multiple posting. It is my mistake that i haven't noticed that policy, i signed up 2 years ago, so...u get the picture... Thanks for merging the two threads, really appreciate it... :)

Well, if you haven't read the question, that already 'posted twice' i asked for help! that is why i made the post. can't fathom why would you go into all that ''if you claim then do it your own'' and what not. just don't reply!

thanks Jadaav!
