Hi,
I'd like to get a power series solution to the following differential equation:
D[a[r],{r,2}] + (D[a[r],{r,1}])/r - 0.5 a[r] + (a[r])^3/(1+(a[r])^2) = 0
The boundary conditions are
a[0] = 2.5
a[Infinity] = 0
da |
-- | = 0
dr | r = 0
da |
-- | = 0
dr | r = Infinity
My attempts to solve this problem have been unsuccessful.
Any help will be most appreciated.
Sincerely,
Javid Atai
