Why not just start by solving the DE:

via integrating factor and obtain the two solutions. What can you say about either solution at x=0? - Jan 21st 2010, 12:20 PMkaboose786

Ok, then here's how I'd do (A):

and dividing by :

for which the integrating factor is so we have:

which the left side is the differential of so:

or:

and if then I can let and obtain the solution . However, if say for example, then I'd obtain which has no solution.

Ok, so I'm a little uneasy about dividing through by in the first step since this is valid if then obtain the solution and solve it for .
