ok im not sure how to start this problem....
the term in front of the y'' is messing me up...any thoughts? anybody? thanks in advance
This is the Legendre differential equation. Use a power series solution.

I'm not getting your recursion relation. Let me briefly plot out my own work. I am putting l(l + 1) = 90.
So
Change the dummy variable in the first term:
(Note that the first two terms of the first sum are 0. So relabeling...)
Or (Thank God for cut and paste!)

ok so in this problem i think i am getting it, i just need help simplifying the problem down..
here is the problem..
this is what i got so far....
i need to get this problem down to where i can solve for
[IMG]a_{n+2}[/IMG]
any help would be greatly appreciated...
Let's suppose to search a solution in the form...
(1)
... and to know the 'initial conditions' and ... the others are found from the DE as follows...
... and so one...
Please revise my computation [and also try to procede...] because an 'old wolf' like me doesn't excell in computation ...
Kind regards
Is there something wrong with your original thread?
Please do not double post. If you have more questions about a problem then post them in the original thread.
