for n=1 : In [14]: dsolve(f(x).diff(x, x)+2/x*f(x).diff(x)+f(x),f(x)) > Out[14]: > C₁⋅sin(x sqrt(3)) + C₂⋅cos(x⋅sqrt(3) ) sin(x)/x (at least for the usual bc) is the solution -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
