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 jav124 at rsphy3.anu.edu.au
