Find the recurrence relation for the coefficients of a power series of y about the given point Xo given the equation.
I am not sure what to do with the
Thanks for any help.
Hello,
it's , not
Let
Hence
and
The equation is now :
Distribute the factors :
Change the indices so that you have in all sums :
-----------------------------------------------------------
Now, change the starting n's in the sums, so that they start at the same point (namely n=2)
Similarly, we have :
-----------------------------------------------------------
So we have the new equation :
Group the terms :
Now you'll have to use the initial conditions to find a recursive relation for
Hope that helps
